Cyclone Amphan is Intensifying as a Serious Storm Surge, Heavy Rain and Wind Threat to India, Bangladesh #Cyclone #Amphan #India #Bangladesh

Cyclone Amphan is quickly strengthening in the Bay of Bengal as it tracks toward India, Bangladesh and Myanmar as a serious threat to one of the world’s most vulnerable populations to cyclones.

Cyclone Amphan (pronounced AM-pun) is currently in the central Bay of Bengal and will track generally northward this weekend and then a turn toward the north-northeast is likely. Its exact track remains uncertain and will determine where the greatest threat from this system will be.

Atmospheric conditions are favorable for development and sea-surface temperatures are very warm. Rapid intensification is a possibility and this tropical cyclone needs to be monitored closely.

Amphan is becoming a hurricane strength system, but could become a major hurricane equivalent system by early Tuesday.

The exact track remains uncertain and as a result areas from northeastern India into Bangladesh and northwestern Myanmar need to be prepared.

As the cyclone approaches the coast on Tuesday night, strong winds, very rough sea conditions, storm surge and heavy rain are likely across Odisha and West Bengal coasts. The Indian Meteorological Department has issued an orange alert to both Odisha and Gangetic West Bengal (South Bengal). The alert urges the residents to be prepared for gale winds and very heavy rainfall.

A red alert has been issued for Gangetic West Bengal, which urges residents to take action to protect themselves from the extremely heavy rainfall and severe winds forecast for that day.

Sailors and fisherman in Bangladesh have been told to not venture into the Indian Ocean.

Depending on where it makes landfall, significant storm surge is possible, which could be destructive. Bangladesh is particularly vulnerable to dangerous storm surge flooding.

Heavy rainfall with the threat of flooding is also a serious concern. It is too early to know how much rain will fall but areas in yellow, orange and red in the map below have the greatest chance of flooding rain.

Heavy rain and gusty winds are also expected this weekend over Andaman and Nicobar Islands.

Strong, gusty winds are also anticipated. Winds near hurricane force are possible, especially in areas closer to where the center of the storm tracks.

The name Amphan is suggested by Thailand and will be the last name from the original list of 64 cyclone names proposed back in September 2004 for storms over the north Indian Ocean. The WMO guidelines stipulate that the countries in the region must name storms in any ocean basin. For the northern Indian Ocean, now thirteen countries suggest the names. The IMD’s regional specialised meteorological centre (RSMC) in New Delhi monitors the cyclogenesis, issues advisories and names the cyclones.

STORM DENNIS UPDATE: Flood alert issued for parts of Greater Manchester as Storm Dennis hits #StormDennis #SevereAlert #Flooding #GreaterManchester #Lancashire #uk

Severe Flood Warning

A flood alert has been issued for parts of Greater Manchester and Lancashire as Storm Dennis hits.

The alert covers parts of Oldham, Bolton, Rochdale, Haslingden, Ramsbottom and Rawtenstall.

The area is known as the ‘Upper River Irwell Catchment’.

“Flooding of low lying land, roads and farmland is expected this evening and tomorrow morning,” according to the Environment Agency.

There is a possibility of flooding on ‘land and roads’ around the rivers Beal, Roch and Croal and Limy Water.

“Our incident response staff are closely monitoring weather forecasts and river levels and will issue flood warnings if necessary”, the government website warns.

The alert was issued just before 7pm tonight (Saturday).

In Lancashire, a flood warning has been issued for Waterfoot, a small town between Rawtenstall and Bacup.

There is risk of the River Irwell flooding as a result of heavy rain caused by Storm Dennis.

“We believe there is a possibility of flooding for properties adjacent to the A681 Bacup Road. We expect river levels to remain high throughout the weekend”, the government website says.

A yellow weather warning for wind and rain is in place from tonight until Sunday afternoon in Greater Manchester.

There is an amber weather warning for rain in place in parts of Lancashire including Bacup and Burnley.

STORM DENNIS UPDATE: Hundreds of flights cancelled in the UK and army called in ahead of heavy winds and flooding #StormDENNIS #flights #planes #cancellations #army #SevereAlert #FloodAlert #gales #UK

Storm Alert

Warnings are in place across the whole of the UK, while a month’s worth of rainfall is expected in places.

Hundreds of flights have been cancelled and the army has been called in as Storm Dennis prepares to hit the UK with strong winds and flooding.

The UK is bracing for disruption as the “perfect storm” approaches, bringing gusts of up to 70mph (113kmph).

The storm could bring a month’s rainfall in one day and some parts of the country could see up to 12cm (4.7in).

More than 230 easyJet flights in and out of the UK have been cancelled due to the weather on Saturday.

British Airways has said most of its flights are scheduled to go ahead as planned, but it is expecting disruption due to strong winds.

As of 9.30am on Saturday, there were 14 flood warnings – meaning people should take immediate action as flooding is expected – and 140 flood alerts, which means flooding is possible.

Forecasters have issued separate weather warnings for rain and wind covering most of the UK until Monday.

This includes amber warnings from midday on Saturday over southern Scotland, northern England, Wales and part of the South West saying that flooding could cause a danger to life.

Troops are being deployed to help with flood preparations in the Calder Valley in West Yorkshire.

The Ministry of Justice has said 75 personnel based in Catterick and 70 reservists from Yorkshire are constructing around 700m of barriers, helping to repair defences and lay down sandbags.

Calderdale Council leader Tim Swift said: “The presence of army officers in Calderdale will be a reassuring sight for the many residents and businesses who are still recovering from Storm Ciara and preparing for Storm Dennis.

“Council staff, partners, volunteers and community groups have worked tirelessly all week and will continue to work around the clock for as long as necessary to help keep people safe and to manage the flood risk.”

A Royal Navy ship is assisting in a search and rescue operation off the coast of Margate, Kent, after a man was reported overboard from a vessel at around 5:41am on Saturday.

It it is not clear if the incident is connected to Storm Dennis.

RNLI lifeboats, a police boat and the coastguard helicopter are assisting with the Navy ship with the search.

The Met Office says Storm Dennis poses a greater risk of widespread flooding than Storm Ciara the weekend before.

The Environment Agency (EA) said this is due to rain falling on already saturated ground.

Power cuts are also expected and there is a good chance train and buses will see cancellations or delays and roads closed.

A punishing cold front has seen record snowfall on Taiwan’s highest peak of Yushan (玉山), and an “orange” cold alert issued for the counties of Hsinchu, Miaoli, and Taoyuan.

This means that temperatures could well drop below 6 degrees Celsius in these areas, from Saturday night to early Sunday morning, according to the Central Weather Bureau (CWB).

In addition, there was a “yellow” alert for Taipei, New Taipei, Keelung, Hsinchu, Taichung, Changhua, Nantou, Yunlin, Chiayi (city and county), Tainan, Kaohsiung, Yilan, Hualien and Kinmen – meaning temperatures could drop below 10 C in these cities and counties.

Yushan, the nation’s highest mountain at 3,952 meters (12,966 feet) above sea level, had experienced intermittent snow over a 17-hour period. This saw snowfalls of up to 25 centimeters, a record amount, stretching back to 20 years ago.

Days of heavy rain has caused flooding in parts of Trinidad.

Flooding was reported in Pernal, Debe, Barrackpore, Siparia an Princes Town. Trinidad and Tobago’s Ministry of Rural Development and Local Government said that communities in the Penal/Debe Regional Corporation (PDRC) had been worst affected. Schools have been closed in affected areas.

“At this time, 15 families have been evacuated. Shelters are open, however some roads remain impassable to low vehicles. Disaster Management officials are on the ground and continue to partner with the Trinidad and Tobago Defence Force to assist residents who are stranded. Community Emergency Response Team (CERT) volunteers, trained by the Ministry in emergency response, have also participated in relief efforts,” the Ministry added.

Trinidad and Tobago Meteorological Service said that Penal recorded 127.2mm of rain in 2 days.

The service issued several Yellow level flood warnings. However, warning have since been upgraded to the higher Orange level as flood waters are still rising in some areas.

Trinidad and Tobago Meteorological Service said that the Caroni River was at maximum capacity and had overflowed onto its banks and some low lying surrounding areas. Local media said flooding in Siparia was caused by the overflowing Tunaco River. The flood situation has been compounded by the occurrence of spring tides.

#Aviation alert raised to #Orange as #smoke #eruption at #MetisShoalVolcano in #Tonga

An intermittent smoke eruption towering to 15,000-17000ft above the summit of the Metis Shoal Volcano, Ha’apai, this morning, has an increased likelihood of an eruption, with an aviation VONA alert now increased to Orange, the Tonga Meteorological Service advised at 10:20am.

Metis Shoal submarine volcano is located near Kao in Tonga’s Ha’apai Group, and is famous for its previous pumice eruptions that have created large pumice rafts.

Real Tonga pilots flying between Tongatapu and Vava’u on flights R4801 and R4802 this morning observed the intermittent smoke eruption, with continuous white plumes of wispy ash cloud.

“We just reconfirmed with the pilot on his way back that 25-30nm north of Kao, towering smoke erupting up to 15,000-17,000ft,” Tonga Met reported this morning, before upgrading an earlier Yellow alert to Orange.

Tonga Met Director, ‘Ofa Fa’anunu said that so far there had been no earthquakes detected in the area of the smoke eruption.

“The Town Officer of Fotuha’a Island, Sifa Fuakolo, first reported to us 8:30pm last night but [we] couldn’t verify till this morning’s Real Tonga flight.”

He said Tonga Met will issue a new Volcano Observatory Notice for Aviation (VONA) this evening, after domestic flights come in and any other shipping reports or observations are received.
