AS-4 has moved N/NW in the last 6 hrs, and at 10 pm Tuesday, is located at 16.2N and 66.3E. That would mean 750 kms W/NW of Goa and 900 kms South of Karachi.

The distinguishing part is the centre, though having 35 knts winds, is relatively free of major clouding. A spiral band, 360 kms to the NW of the centre, is moving towards coastal Sindh. System is still at 998 mb with cyclonic winds of 35 knts and gusting to 45 knts.

AS-4 is set to start weakening from Wednesday. The clouds spiral rushing into coastal Sindh will produce extremely stuffy weather in Karachi tonite (Tuesday). Possiblity of light rain will make it uncomfortable. For Karachi, I do not expect the rain to persist much beyond mid day on Wednesday, though cloudy weather will linger on for another 2 days.

Another system is forming in the Southern Bay at 89E. Still in the initial stage, will discuss the developments on Wednesday.

Mumbai was the limit on Tuesday. Hot, humid and partly cloudy ! Produced the most unbearable weather conditions.

With the high hittting 36.8c, +4c above the normal, Mumbai was the hottest in Asia on Tuesday. Thankfully it is not the hottest in the Northern Hemisphere, where Tambacounda (Senegal) was at 39c.

For India, the 2nd hottest was a far 35.2c at Surat.

Hot and humid partly cloudy weather expected into Wednesday and Thursday for Mumbai, with the day hitting 35c. Night will be an unbearable 26c. Expect a few degrees drop in temperature on Friday

April normal nights are 26c for Mumbai, and the nights rise to 27c after the first week of May. The normal day for April is 33c, and 34/35c for May.

Mumbai was in the 37c - 26c range on Tuesday ! 90% humidity at Colaba on Tuesday morning and 76% in the evening ! S'Cruz was at an avg humidity of 65%.
