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.

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.
