Low-pressure area over Bay of Bengal

-

As expected, a low-pressure area formed over South Andaman Sea and adjoining southeast Bay of Bengal on May 1.
Associated cyclonic circulation extends up to 4.5 km above mean sea level. An IMD bulletin said that the low-pressure area is very likely to become more marked over the same region during next 48 hours, concentrate into a depression over Andaman Sea and adjoining Southeast Bay of Bengal during subsequent 48 hours and likely to intensify further thereafter.
It is very likely to move North-North-Westwards gradually till May 5.
Under the influence of trough / wind discontinuity, Peninsular India is likely to experience isolated to scattered rain / thundershowers during next five days with isolated heavy rainfall over Tamil Nadu and Puduchery, Kerala and Mahe and Coastal Karnataka during next 24 hours.
Ongoing intense thunderstorm activity over Northeast India and adjoining eastern states likely to continue during next five days.
A fresh western disturbance is likely to cause scattered to fairly widespread rain / thundershowers over Western Himalayan region and adjoining plains of North West India from May 3 onwards, it said.

A low-pressure area is likely to be formed over the South-East Arabian Sea in the first week of June. The Extended Range Outlook of RSMC said that the likelihood of MJO ’s further eastward propagation into phase-2 as well as the probable strengthening of cross equatorial south-westerlies, it is likely that a low-pressure area may form over southeast Arabian Sea towards the end of the week May 29-June4. Meanwhile, a tweet by Jason Nicholls, Senior Meteorologist at AccuWeather, said that MJO pulse approaching the Indian Ocean can lead a low and perhaps a cyclonic storm spinning up over the Arabian Sea near Lakshadweep in early June. The tweet said that the exact track of low is unclear so areas from Gujarat and coastal Pakistan to Oman will need to monitor. Even the cyclonic strike probability of ECMWF also predicts a tropical cyclonic activity during the above-said period.
