Maha to weaken as severe cyclone while bearing down on Gujarat coast

Forecasters are surprised to watch very severe cyclone Maha intensify into an extremely severe cyclone by early this (Monday) morning with prospects for further strengthening in the East-Central Arabian Sea.

The India Meteorological Department (IMD) witnessed the mid-sea drama unfold, and located the extremely severe cyclone early in the morning 660 km West-South-West of Veraval (Gujarat); 700 km West-South-West of Diu; and 640 km West-South-West of Porbandar.

U-turn, as scheduled

The IMD has put Maha watch for further intensification till tomorrow (Tuesday) morning and weaken gradually thereafter. It is forecast to move West-North-West slowly through the rest of the day and into the night, re-curve (take a U-turn) towards to East-North-East twards India's coast and move in rapidly thereafter.

It is expected to cross the Gujarat coast between Diu and Porbandar as a severe cyclone with maximum sustained wind speed of 100-110 km/hr gusting to 120 km/hr by Wednesday midnight or early on Thursday.

 

The pattern of intensification as projected in Maha's case does not happen so often. It is not too long ago that  supercyclone Kyarr pulverised the same waters and therefore it was natural to expect that the heavy rain from it would have cooled the sea surface, limiting the scope for intensification of successor storms.

The very fact that Maha was put under watch by the IMD for intensification as a very severe cyclone so early into its initiation had caught many seasoned weather watchers unawares.

After getting its forecasts spot on with respect to supercyclone Kyarr, there was no cause for suspecting IMD's forecasting capabilities, as subsequent tracking of successor very severe cyclone Maha has proved till date.

But, evidently, its further intensification as an extremely severe cyclone (next only to a supercyclone) would have even surprised even IMD, prompting it to watch for signs of Maha's further strengthening.
