Heavy rains threaten more as low nears West Bengal!


METD WEATHER

Severe Weather Forecaster
UPDATE ON THE LOW PRESSURE
THE 12Z THAI MAP HAS SHOWN THAT THE LOW AGAIN HAS BEEN INTENSIFIED TO 998MB! HOWEVER THE SYSTEM HAS LOST ALL ITS SYMMETRIC SHAPE DUE TO THE 10KT+ WIND SHEAR WHICH IS LOW BUT WHEN HELPED WITH ZERO CONVERGENCE AND DIVERGENCE IS EFFECTIVE
LOW TYPICALLY STRENGTHEN DUE TO MOIST AIR MASS FEED WITH LOW LEVEL CIRCULATION INTENSIFICATION WHICH HAPPENS AS MORE MOIST AIR RISES AND THEN COLLIDES WITH COOL AIR RELEASING THE LATENT HEAT
WITH THIS SETUP, PRESSURE WILL RISE ON 8TH OCT BUT I BELIEVE IT WILL STRENGTHEN SOME BEFORE HAVING A COASTAL LANDFALL ON 8TH
SO SYSTEM IS FULL OF SURPRISE

COASTAL ORISSA ( ESP- BALESHWAR,BHADRAK,PARADWIP ETC ON COASTS )
