Super typhoon (class-topping Category-5 on storm intensity scale) Bopha has weakened after hitting the Philippines but is expected to enter South China Sea soon.

It is being watched for signs of re-intensification, but most models are of the view that it would retain category-2 strength on a storm intensity scale of 1 to 5.

LIKELY TRACK

The likely track is west-northwest towards Taiwan and adjoining Chinese mainland.

Projections as of Tuesday showed a storm ‘pulse’ crossing Indo-China and heading into extreme South Bay of Bengal towards southern Sri Lanka.

Adjoining coast of India just to the north is not likely to get impacted in any significant manner, these projections showed.

In fact, the US National Centres for Environmental Prediction indicated that peninsular India may stay dry during the period from December 12 to 20.

Meanwhile, a prevailing low-pressure area and a resident ‘trough’ of lower pressure in the Bay of Bengal have been bringing heavy rain into South-east coast.

HEAVY RAIN

Many places over Tamil Nadu and a few places over south Andhra Pradesh received heavy to moderate rainfall during the last two days.

South interior Karnataka, coastal Karnataka, Kerala and Lakshadweep too witnessed scattered showers.

Tirupati (11 cm) and Chennai (8 cm) accounted for the heaviest rain recorded during the 24 hours ending Tuesday morning.

Other major receiving stations were (in cm of rain) Numgambakkam (4), Nellore (3), Vedaranniyam and Vellore (2 each).

WEATHER SYSTEMS

The India Meteorological Department has forecast heavy rain at over coastal Andhra Pradesh, Rayalaseema and north Tamil Nadu for a couple of days more.

Thundershowers are likely at many places over coastal Andhra Pradesh and Rayalaseema.

A few places over Tamil Nadu, Kerala, Karnataka and Telangana also may witness occasional showers during this period.

Isolated showers have been forecast for Maharashtra, Goa, Odisha and south Chhattisgarh.

An extended forecast valid until Tuesday next said that thundershowers might occur at a few places over peninsula.
