It is likely to cross Saurashtra and Kutch around June 15 noon with maximum sustained wind speed of 125-135 kmph gusting to 150 kmph. Isolated heavy rainfall is very likely over remaining districts of Saurashtra and north Gujarat region on June 15.
That said, the IMD expects heat wave conditions to continue over parts of Northwest, East and North peninsular India during next 3-5 days. No significant change is expected in maximum temperatures over the country except over Gujarat where these are likely to fall by 4-6°C during next 5 days. Hot and humid conditions very likely over Tamil Nadu, Rayalaseema, Madhya Maharashtra and Marathwada during next 3 days.
