Tropical Storm Andrea to make landfall within hours-forecaster

June 6 | Thu Jun 6, 2013 11:39pm IST

(Reuters) – The center of Tropical Storm Andrea will reach the northern part of Florida in the next few hours, then will move in a northeasterly direction near the east coast of the United States through Saturday, U.S. government forecasters said on Thursday.

Andrea, the first tropical storm of the 2013 Atlantic hurricane season, was swirling about 35 miles (55 km) west- southwest of Cedar Key, Florida, and packing maximum sustained winds of 60 miles per hour (95 kph), the Miami-based National Hurricane Center said.

A tornado threat continued for much of the Florida peninsula, the NHC said.

Tropical Storm Andrea Pounds Parts of Florida

The storm has brought rain, heavy winds and tornadoes

Updated Friday, June 7, 2013, 3:36 a.m.

(NOAA)

MIAMI (AP) – The first named storm of the Atlantic season hammered Florida with rain, heavy winds, and tornadoes Thursday as it moved toward the coast of Georgia and the Carolinas, promising sloppy commutes and waterlogged vacation getaways through the beginning of the weekend.

Tropical Storm Andrea was losing intensity late Thursday and not expected to strengthen into a hurricane but forecasters warned it could cause isolated flooding and storm surge over the next two days.

Tropical storm warnings were in effect late Thursday for the East Coast from Flagler Beach, Fla., to Cape Charles Light in Virginia, the Pamlico and Albemarle sounds and the lower Chesapeake Bay south of New Point Comfort. A tropical storm warning means that tropical storm conditions are expected somewhere inside the warning area within a day and a half. A warning for Florida’s west coast was lifted late Thursday, but forecasters advised that heavy rains were continuing well away from the storm’s center.

As of 11 p.m. EDT Thursday, the U.S. National Hurricane Center in Miami said Andrea was about 40 miles (64 kilometers) west of Jacksonville, having made landfall hours earlier in Florida’s Big Bend area. Andrea’smaximum sustained winds had fallen to 45 mph (72 kph) and it was moving northeast at 15 mph (24 kph).

RELATED ON SKYE: The Most Devastating Hurricanes in U.S. History
Hurricane AndrewRains and winds from the storm were forecast to sweep northward along the Southeastern U.S. coast Thursday night and Friday. The storm was expected to lose tropical characteristics Friday night as it moves through the eastern United States.

Florida Gov. Rick Scott said earlier Thursday that one of the biggest risks associated with the storm for Florida was the chance of tornadoes, eight of which had been confirmed across the state. Scott urged residents to remain vigilant.

“This one fortunately is a fast-moving storm,” he said. Slower-moving storms can pose a greater flood risk because they have more time to linger and dump rain.

In The Acreage, a part of Palm Beach County, Fla., pre-kindergarten teacher Maria Cristina Arias choked back tears and clutched valuable personal papers as she surveyed the damage done by a tornado to her five-bedroom home when she was away. Windows were smashed and a neighbor’s shed had crashed into her bedroom.

“It’s all destroyed,” she told The Palm Beach Post. “This is unbelievable. I don’t know what we’re going to do.”

Her 19-year-old son, Christian, was sleeping when he heard a loud noise.

“It was really scary,” said the teen, who wasn’t hurt. “It sounded like something exploded. I didn’t know what was going on.”

Another threat to Florida’s coast was storm surge, said Eric Blake, a specialist at the Hurricane Center. The center said coastal areas from Tampa Bay north to the Aucilla River could see storm surge of 2 to 4 feet, if the peak surge coincides with high tide.

Gulf Islands National Seashore closed its campgrounds and the road that runs through the popular beach-front park Wednesday. The national seashore abuts Pensacola Beach and the park road frequently floods during heavy rains.

On May 23, 2013 NOAA’s Climate Prediction Center released its 2013 Atlantic Hurricane Season Forecast, predicting an active season. NOAA classifies 12 of the 18 seasons since 1995 as above normal, with eight being very active.

NOAA predicts (with 70% like hood) 13 to 20 named storms total, between 7 and 11 of which will be hurricanes, with 3 to 6 major hurricanes. An average for Atlantic hurricane season is 12 named storms, 6 hurricanes and 3 major hurricanes, so we can say NOAA calls for an above-average active season. NHC points that this year’s season may unleash stronger storms than in the last couple of years.

After Hurricane Sandy experience, NOAA warns that tropical storm and hurricane impacts are not limited only to the coastline, but strong winds, torrential rain, flooding and tornadoes often threaten further inland areas.

WATCHING THE WORLD EVOLVE AND TRANSFORM

Tropical Cyclone Mahasen fully dissipated after weakening into tropical storm on May 16, 2013. Luckily, its impact was far less damaging than initially expected. Mahasen veered west of its predicted path after dumping heavy rains over bay of Bengal coastal areas.

Mahasen hit land with maximum wind speeds of about 100 km/h (62 mph) and quickly weakened. There was no major tidal surge due the low tide in time of Mahasen’s landfall. However, many low-lying areas and islands were inundated by a surge during the storm. More than 49,000 thatched houses were destroyed.

The cyclone spared major populated areas in Bangladesh, including Chittagong and the seaside resort of Cox’s Bazar. By the time Mahasen hit Chittagong and Cox’s Bazar, wind speeds had plunged to 25 km/h (16 mph).

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this natural-color image the day that Mahasen came ashore. Clouds stretched across Bangladesh, northeastern India, and northwestern Burma.

The TRMM satellite had two very informative views as deadly tropical Cyclone Mahasen was moving toward and then over Bangladesh. TRMM passed above Mahasen on May 15, 2013 at 2133 UTC and saw Mahasen again on May 16, 2013 at 0406 UTC after the tropical cyclone’s center passed over Bengladesh’s Ganges Delta.

Alvin had strengthened to a Tropical Storm on May 15, 2013 and now has weakened and is considered a Post-Tropical Cyclone. With the excessive wind shear and cooler water, the storm has dissipated into just a weak low pressure.

According to Tropical Weather Outlook by US National Hurricane Center, an area of low pressure associated with the remnants of Alvin is located about 800 miles southwest of Manzanillo, Mexico. The system continues to produce a large area of disorganized shower and thunderstorm activity.

Cyclone Mahasen buffets Bangladesh coast, six dead

 

 

 

 

CHITTAGONG, Bangladesh | Thu May 16, 2013 7:48am EDT

(Reuters) – Cyclone Mahasen buffeted Bangladesh’s low-lying coast on Thursday, killing six people after forcing many thousands into emergency shelters, but authorities downgraded warnings later in the day as the storm lost strength.

A storm surge did cause some flooding along the coast at high tide and thousands of rickety huts were destroyed by torrential rain and wind, but the devastation was not as bad as had been feared.

Neighboring Myanmar, where there were fears for the safety of many thousands of internally displaced people living in camps, also appeared to have been largely spared.

The storm was moving northeast, into northeastern India, as it lost strength, meteorological officials said.

“It has now crossed over coastal areas and is a land depression over Bangladesh and adjoining areas of India and will gradually weaken further,” Mohammad Shah Alam, the director of the Bangladesh Meteorological Department, told Reuters.

Earlier, winds of up to 100 kph (60 mph) lashed the coast, whipping up big waves as the United Nations warned that 4.1 million people could be threatened.

A Bangladeshi army official at an control center set up to help with relief work said six people had been killed.

Some media said the death toll was nine, with some of them killed by falling trees.

About 50 people were injured, according to media reports.

Bangladesh, where storms have in the past killed many thousands of people, has more than 1,400 cyclone-proof buildings and many people moved into them as Mahasen approached.

THE WATCHERS

WATCHING THE WORLD EVOLVE AND TRANSFORM

Tropical Cyclone Mahasen (01B) is now centered several hundred miles south of Kolkata, India, and will impact areas from northeastern India to Bangladesh and Myanmar over the next few days. The system is about to enter  into an area of warm sea surface temperatures and lower wind shear which will intensified the cyclone and give it opportunity to become even better organized. Landfall is expected to occur on May 16, 2013 with most forecast models putting the path between Chittagong (Bangladesh) and Maungdaw (Myanmar).

On May 13, 2013 the Suomi NPP satellite caught an interesting glimpse of the storm as it moved off the eastern coast of India. The VIIRS Day-Night Band was able to resolve lightning flashes towards the center of the storm, along with mesopheric gravity waves emanating outwards like ripples in a pond. These gravity waves are of particular interest to air traffic controllers so assist in identifying areas of turbulence. (Credit: NOAA/NASA/VIIRS)

TC Mahasen will bring life-threatening conditions to millions of people from northeastern India and into Bangladesh and Myanmar. Due the low elevations of this region (mostly shallower than 200 meters), flooding, mudslides and storm surge present the greatest threats. These areas have been hit by some of the deadliest cyclones across the globe.

According to GDACS, up to 22.3 million people people can be affected by wind speeds of tropical storm strength or above. In addition, 4.1 million people people are living in coastal areas below 5m and can therefore be affected by storm surge.

The highest impact, surge and rainfall predictions are for the Chittagong and Cox’s Bazaar areas of Bangladesh but there are serious concerns for Rakhine State where there are more than 140,000 IDPs. (Credit: OCHA/ReliefWeb)

Torrential rains caused floods and landslides across Sri Lanka, which are responsible for seven reported deaths. Several overcrowded boats carrying hundreds of evacuees capsized off the coast of western Myanmar after the lead boat crashed into rocks and more than 50 people are feared dead. Myanmar state television reported Monday that 5,158 people were relocated from low-lying camps in Rakhine state to safer shelters. But far more people are considered vulnerable.

According to latest report by Joint Typhoon Warning Center (JTWC), TC Mahasen is located approximately 246 nm southward of Calcutta, India. The system is moving north-northeastward at speed of 12 knots. Upper level analysis indicates an anticyclone to the east of the system continues to move into better vertical alignment with the low level circulation center, leading to a decrease in vertical wind shear to low levels (10 knots).

Back

Updated: Thursday, 16 May, 2013 at 11:38 UTC
Description
Cyclone Mahasen has struck the southern coast of Bangladesh, lashing remote fishing villages with heavy rain and fierce winds that flattened mud and straw huts and forced the evacuation of more than 1 million people. The main section of the storm reached land on Thursday and immediately began weakening, according to Mohammad Shah Alam, director of the Bangladesh meteorological department. However, its forward movement was also slowing, meaning that towns in its path would have to weather the storm for longer, he said. Even before the brunt of the storm hit, at least 18 deaths related to Mahasen were reported in Bangladesh, Burma and Sri Lanka. The storm could bring life-threatening conditions to about 8.2 million people in Bangladesh, Burma and north-east India, according to the UN’s Office for the Co-ordination of Humanitarian Affairs. Danger was particularly high for tens of thousands of displaced Rohingya people living in plastic-roofed tents and huts made of reeds in dozens of refugee camps along Burma’s western coast.

Driven from their homes by violence, members of the Muslim minority group refused to follow evacuation orders. Many distrust officials in the majority-Buddhist country, where Rohingya have faced decades of discrimination. UN officials, hoping they would inspire greater trust, fanned out across the area to encourage people to leave. Early on Thursday, the cyclone battered the southern Bangladesh fishing village of Khepurpara along the Bay of Bengal with 62mph (100km/h) winds and was heading east toward the city of Chittagong and the seafront resort town of Cox’s Bazar. River ferries and boat services were suspended, and scores of factories near the Bay of Bengal were closed. The military said it was keeping 22 navy ships and 19 air force helicopters on alert. Tens of thousands of people fled their shanty homes along the coast and packed into cyclone shelters, schools, government office buildings and some of the 300 hotels in Cox’s Bazar to wait out the storm. Some brought their livestock, which took shelter outside.

NASA Goddard MODIS Rapid Response TeamCHITTAGONG, Bangladesh – Bangladesh warned millions of people Monday, May 13, that a cyclone could barrel into their coastal homes later this week as authorities in Myanmar began moving potential victims to higher ground.

The Bangladesh Meteorological Department said that while it was too soon to predict where cyclonic storm Mahasen would hit, it raised its alert to four, meaning “there are increased chances that the cyclone will hit the coast”.

The department’s deputy head Shamsuddin Ahmed said Mahasen was currently in the Bay of Bengal, 1,355 kilometers (840 miles) south west of Chittagong, and could make landfall in the southeast of the country on Thursday.

“Mahasen is still a cyclonic storm. It has not gathered enough strength to become a severe cyclone. But it is likely to intensify further,” he told AFP.

The government has made preparations for the cyclone, but will wait until it has firmer information as to where it would make landfall before issuing any evacuation order, Chittagong provincial administrator Muhammad Abdullah said.

“We’ve alerted the people living in coastal areas, but have not evacuated any of them because we still don’t know where the cyclone will hit. But we’re fully prepared to face any situation,” he told AFP.

He said authorities have set up logistics support and kept cyclone preparedness volunteers, doctors and officials ready for the cyclone.

Around 30 million of Bangladesh’s population of 153 million live along the coast, and Chittagong is the country’s second largest city.

Monday’s warning from Bangladesh echoed a similar alert from Myanmar’s Department of Meteorology and Hydrology at the weekend.

NASA Sees a Strengthening Tropical Cyclone Mahasen

The first tropical cyclone in the Northern Indian Ocean this season has been getting better organized as seen in NASA satellite imagery. Tropical Cyclone Mahasen is projected to track north through the Bay of Bengal and make landfall later this week.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Aqua satellite captured a visible image of Tropical Cyclone Mahasen in the Northern Indian Ocean on May 15 at 07:55 UTC (3:55 a.m. EDT). The image was created by NASA’s MODIS Rapid Response Team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland and showed Mahasen had consolidated over the last two days. Mahasen appeared rounded and its strongest thunderstorms appeared to be surrounding the center of circulation. The center also appears to be topped with a large dense overcast. The image showed Mahasen’s center was northeast of Sri Lanka, although a band of strong thunderstorms south of the storm’s center were affecting the island nation at the time of the image.

Tropical Cyclone Mahasen targets India, Bangladesh, Myanmar

Tropical Cyclone Mahasen (TC 01B) is getting better organized. Winds are predicted to increase to hurricane force as the system moves further northward into the Bay of Bengal. TC Mahasen is now located east-nort​heast of Sri Lanka and is expected to impact areas from northeast India to Bangladesh and Myanmar.

According to latest report by Joint Typhoon Warning Center (JTWC), TC Mahasen is located approximately 721 nm southward of Calcutta, India. The system is moving north-northwestward at speed of 6 knots. Maximum sustainable winds are 55 knots with gusts up to 70 knots.

The cyclone is beginning to round the western edge of the subtropical ridge to the east. It is expected to slow down over the next 24 hours as it makes the turn before recurving northeastward on the poleward side of the ridge axis. TC Mahasen will gradually intensify as the vertical wind shear relaxes along the ridge axis. Additionally, the poleward outflow is expected to open up as the system becomes exposed to the prevailing westerlies.

Animated infrared satellite imagery shows the system has regained a central dense overcast feature that has, once again, obscured the low level circulation center. Upper level analysis indicates the system is 7 degrees south of the ridge axis in an area of moderate (20 knot) easterly vertical wind shear. However, the vertical wind shear is offset by robust westward outflow.

After the next 72 hours, TC Mahasen will gradually weaken as vertical wind shear increases before making landfall near Chittagong, Bangladesh. Land interaction will rapidly erode and dissipate the system.

According to Indian Meteorological Department (IMD), under the influence of this system, rainfall at many places with isolated heavy rainfall would occur over Andaman and Nicobar Islands during next 48 hours. Squally winds speed reaching 40-45 km/h gusting to 60 km/h would prevail along Andaman and Nicobar Islands during next 48 hours. Sea condition will be rough to very rough along and off Andaman and Nicobar Islands during this period.
