DEMS-RSMC TROPICAL CYCLONES NEW DELHI 21- 10- 2008.



TROPICAL WEATHER OUTLOOK FOR NORTH INDIAN OCEAN (THE BAY OF BENGAL AND ARABIAN SEA) VALID FOR NEXT 24 HOURS issued at 1400 utc OF 21 oCTOBER, 2008 based on 1200 UTC of 21 oCTOBER 2008 (.)



THE DEEP DEPRESSION OVER SOUTHWEST ARABAIN SEA MOVED NORTHWESTWARDS AND LAY CENTRED AT 1200 UTC OF TODAY, THE 21ST OCTOBER 2008 OVER SOUTHWEST ARABIAN SEA NEAR LAT. 11.00N AND LONG. 54.00E, ABOUT 400 KM EAST-SOUTHEAST OF ALULA (63200) OF SOMALIA, 650 KM SOUTHEAST OF RIYAN (41443) OF YEMEN AND 650 KM SOUTH OF SALALAH (41316) OF OMAN.

SATELLITE IMAGERIES INDICATE PERSISTANT ORGANISED IN CONVECTION IN ASSOCIATION WITH THE SYSTEM. THE INTENSITY OF THE SYSTEM IS T2.0. SUSTAINED MAXIMUM WIND SPEED IS ESTIMEATED TO BE ABOUT 30-35 KNOTS. STATE OF SEA IS VERY ROUGH TO HIGH AROUND THE SYSTEM CENTRE. THE ESTIMATED CENTRAL PRESSURE IS ABOUT 1000 HPA.

ASSOCIATED BROKEN INTENSE TO VERY INTENSE CONVECTION IS SEEN OVER THE ARABIAN SEA BETWEEN LATITUDE 08.50N AND 14.50N AND WEST OF LONG 54.00 E, NORTHEAST SOMALIA AND GULF OF ADEN. THE DEEP CONVECTION IS SHEARED TO THE WEST OF THE CENTRE OF THE SYSTEM. THE LOWEST CLOUD TOP TEMPERATURE (CTT) DUE TO CONVECTION IS ABOUT -750C TO -800C. VERTICAL WIND SHEAR OF HORIZONTAL WIND OVER THE REGION IS 10 TO 20 KTS AND PAST 24 HRS SHEAR TENDENCY IS -10 TO -20 KTS TO NORTHWEST OF THE SYSTEM. THE SYSTEM LIES TO THE SOUTH OF THE UPPER TROPOSPHERIC RIDGE WHICH ROUGHLY RUNS ALONG 170N.

CONSIDERING ALL THE ABOVE, THE SYSTEM IS LIKELY TO MOVE IN A WEST-NORTHWESTERLY DIRECTION TOWARDS SOUTH YEMEN COAST ACROSS GULF OF ADEN, SKIRTING NORTH SOMALIA COAST TOMORROW, THE 22ND OCTOBER 2008 BETWEEN 0600 AND 0900 UTC.

THE SEA SURFACE TEMPERATURE NEAR THE SYSTEM AND OVER THE REGION TO THE WEST OF THE SYSTEM IS ABOUT 27-280C. AS THE SYSTEM APPROACHES TOWARDS NORTH SOMALIA COAST, IT IS LIKELY TO INTERACT WITH LAND SURFAC AND ENTRAINMENT OF COLD AIR IS ALSO LIKELY. HENCE, FURTHER INTENSIFICATION OF THE SYSTEM IS NOT EXPECTED.

Doesn't make a difference when it's sheared this badly though.

Dozens killed by floods in Yemen

Please turn on JavaScript. Media requires JavaScript to play.

Aerial footage shows the severity of the floods

At least 48 people have been killed or are missing in Yemen, following torrential rains.

Most of the casualties are in the eastern province of Hadhramawt, hit by a tropical storm earlier this week.

An air rescue operation is under way. Damage is extensive because most homes in the area are made of mud brick.

Reports say the floodwaters are threatening the historic high-rise mud buildings of Shibam - a Unesco world heritage site.

A reporter for the Associated Press news agency in Shibam said he had watched a two-storey mud-brick house disintegrate on Saturday.

There has also been severe flooding in the capital, Sanaa, in recent days.

On Saturday at least six aircraft took off from Sanaa carrying tents, food and medicine to Hadramawt province, airport officials told AFP news agency.

Severe flash floods struck Yemen in 2006, leaving several dead and sweeping away buildings.

What was really shocking to read was that NINE people were killed by lightning! :eek: Getting stuck by lightning is a lot more common then everyone thinks me thinks.

Yemen flood death toll rises



PRESIDENT Ali Abdullah Saleh today allocated $US100 million ($148 million) in aid to flood-hit areas of southeast Yemen as the death toll from last week's storms topped 70.

"The president ordered 20 billion rials ($148 million) to be added to the general budget for the reconstruction of Hadramaut and Mahara provinces," the government said.

A relief team rescued two children alive from rubble of a house at Tarim but uncovered 10 bodies of people from the same family who had all died in the floods of Thursday and Friday, an official in Hadramaut province said.

These victims take to 68 the number of deaths caused by the high waters, while another six were struck by lightning during the storms that brought the torrential rain.

Many other people are still missing and thousands are without shelter, the official said.

Rescue teams, chiefly using military helicopters, are continuing operations to help people hit by the flood, especially in isolated villages.

Mr Saleh said yesterday that at least 1700 homes were destroyed or badly damaged as the waters rose while roads and the electricity network were seriously affected.

People who are still cut off are lacking food and drinking water, he said.

Yemen has started to receive help from neighbouring countries.

Following a promise of aid from the United Arab Emirates, Oman announced today the dispatch by air of tents and food.
