After this, the friction effects of land will bring
down storm intensity, but not before generating heavy to very heavy rainfall
over the coastal areas of Tamil Nadu and Andhra Pradesh.
‘Nilam’ is
expected to track north-west from its current being where it is
quasi-stationery (briefly stopped on tracks), JTWC said. The India
Meteorological Department (IMD) too expects the same track for the cyclonic
storm.
The European Centre for Medium-Range Weather
Forecasts also tends to agree with the forecast for another round of
intensification and the north westward track for ‘Nilam’.
But the US National Centre for Environmental
Prediction persists with the odd forecast that takes ‘Nilam’ for landfall over
north-east Sri Lanka and adjoining south-east Tamil Nadu coast.
Subsequently, it breaks up into two, with a
splinter propelling towards Chennai and the other towards coastal
Karnataka-Konkan.
The IMD has warned of heavy to very heavy rainfall
with extremely heavy falls (25 cm or more) at one or two places over north
coastal Tamil Nadu and south coastal Andhra Pradesh during the next two days.
Heavy to very heavy rainfall is expected over
Kerala, north coastal Andhra Pradesh and south interior Karnataka.
Squally winds speed reaching 45-55 km/hr gusting to
65 km/h would prevail along and off north Tamil Nadu, Puducherry and adjoining
south Andhra Pradesh coasts until Wednesday noon. The wind speed would
gradually increase, thereafter, as the system comes closer to coast.
Sea conditions will be very rough to high along and
off north Tamil Nadu, Puducherry and adjoining south Andhra Pradesh coasts.
Fishermen along north Tamil Nadu, Puducherry and
adjoining south Andhra Pradesh coasts have been advised not to venture in to
the sea.
