Squally NE winds are expected along the T.N. coast and Chennai from Thursday

Publishing Next week's expected Developing situation and Weather forecast for the South. Its a 7 day estimate, and will be monitiored as it happens.

As mentioned yesterday, a UAC is likely to form off the South T.N. coast/Sri Lanka around Tuesday, 22nd November. This is likely to descend to form a sea level low in the same region within next 2 days, say around the 24th (Thursday). The said Low is expected to deepen (by then it would be numbered) and cross the Southern coast of T.N.

Squally NE winds are expected along the T.N. coast and Chennai from Thursday.

Hence, the coastal regions of T.N. and Chennai can expect increasing rainfall from Wednesday/Thursday, with heavy falls by Friday. Chennai can expect upto 7 cms on Friday, 25th. Interior T.N. can get meaningfull rains after Thursday thru Sunday.

As the system crosses the coast, the precipitation is expected to spread into North T.N. and S.interior Karnataka around Friday.

Vagaries shall keep track of this, as it is still 5/6 days away.

Vagaries expects this system to cross into the Arabian Sea in the subsequent week , and emerge as a low off the Kerala coast around Tuesday 29th.

Very difficult to foresee the movement and track at this stage (10 days in advance), but current conditonal observations and expected track study indicates a North movement, but a very slim survival chance of more than a couple of days for the system.

North India:

Due to the moving away of the W.D, ground fog occuredin the Punjab, Haryana, Delhi and West U.P. regions on Sunday morning. Visibility was low and up to 50 mtrs. Clear skies and enough moisture will create the perfect conditions for ground fog in the same areas on Sunday night/Monday morning.
