Current
Meteorological Analysis
The current meteorological analysis
and numerical weather prediction models suggest southward shift of monsoon
trough from tomorrow onwards. Subsequently, a low pressure area is likely to
form over west-central and adjoining northwest Bay of Bengal around 27 July.
This development is considered as a signal for revival of monsoon activity
along the west coast and over central & adjoining peninsular India.
Weather Forecast for next One Week
·
Rainfall activity is
likely to increase considerably over Central & adjoining Peninsular India
particularly over Andhra Pradesh and Maharashtra.
·
The rainfall
activity is also likely to increase along the west coast and Gujarat with
possibility of heavy to very heavy falls.
·
The intensity of
ongoing rainfall activity over foothills of the Himalayas & adjoining Gangetic
plains and northeastern states is
likely to decrease from tomorrow onwards.
·
Scattered rain/thundershower activity is likely over
northwest India.
Next Press Release will be issued around 31st
July 2008.
