Cyclone Thane Makes Landfall South of Chennai, 00Z 30 DEC 2011

Per Doppler Radar out of Chennai Cyclone Thane is making landfall this morning South of Chennai. Already there are reports of people needing rescue off the Indian coast as the Severe Cyclone neared Thursday night in to Friday morning.  Still no reports of any casualties and limited reports of damage from this storm yet as day breaks in the region more light will be shed on the impact this storm is making along the East Coast.

At 21Z today JTWC (Joint Typhoon Warning Center) ranked the storm as an equivalent of a Strong Tropical Storm with winds of 60G75kts as it tracked west approximately 75nm to the south of Chennai. Given this track coastal storm surge is still likely to the North of the land falling storm in the city of Cuddallore.  All residents in the region are urged to stay in doors until winds begin to subside as well.  Even in areas farther inland or are rain free gusty winds can still cause loose objects to go airborne causing damage to people or property.

With that said though rainfall is still a big worry today, Chennai itself from reports overnight looks to to have missed the brunt of the rainfall.  Yet to the South convective bands continue to move on shore bringing totals well above 100mm over a course of 6hours across the region.  Low lying areas not only near the coast but also farther inland should be aware of the potential of flash flooding from this storm.

Below is a video update from our partner at 28storms.com

Later today a video update on this storm will be posted as well.

Severe Storms over Queensland Australia

The video above is from the AUS WX CHANNEL during there daily updates.

 

The remnants of TC Grant is causing severe storms across QLD today as it continues to track west. Even the storm is no longer tropical in nature it continues to feed off diurnal instability in the region and moist air being fed in from the Gulf and the Coral Sea.

The BOM has issued the Final Warning as of 12Z.

“Severe thunderstorms are likely to produce damaging winds, very heavy rainfall, flash flooding and large hailstones in the warning area over the next several hours. Locations which may be affected include Warwick, Toowoomba, Dalby, Emerald, Biloela, Blackwater, Stanthorpe, Springsure and Goondiwindi. ”

As stated these storms can produce strong and damaging winds, yet flash flooding is also a major issue in low lying areas near the coast. This not only could occur today but also in to tomorrow as river flow from the table lands begins to push down stream.

Stay tuned tomorrow I will have more information on the severe weather in the region.

Japan Snow Fall Continues, 29 DEC 2011

While Tropical Weather prevails in Australia and the Indian Ocean. Not to mention a developing  Low in the South China (Read Today’s SE ASIA WEATHER UPDATE)  Snow fall continues to hit the west coast of Japan in great numbers. The image to the right shows the snow forecast over the next 6 days noting some of the areas displaying totals above 50cm. This is to add to the overall total in locations nearing 3-4 meters.

This area of the world along the west coast of Japan is historic for its heavy snowfall amounts annually. For people living in the United states the atmosphere effects that take place in Japan are similar to those along the great lakes.  ( I grew up in Buffalo New York) The cold air out of Siberia pushes across the warm waters of the Sea of Japan creating an unstable atmosphere and allowing clouds to condense as the air pushes South West. There are to images below the first of today’s Surface Analysis showing the isobar lines flow going from the NW to the SE and the second Ocean Effect snow diagram displaying many these features that take place.

With that said the snow fall looks to continue for Japan as the Siberian high continues to pump cold dry air towards the south. This is great for skiers and people heading out to enjoy the Sapporo Snow Festival.  Yet can always be a pain for day to day life for the people along the Northern and Western Japan.
