GUWAHATI, May 5 - The impact of cyclone �Fani,� which led to a lot of panic and misery for the people of Odisha, West Bengal, Bangladesh and North East India during the past about 48 hours, is almost over on the NE region. The remnants of the �Fani� system turned into a cyclonic circulation persisting up to 1.5 km above the mean sea level over North Myanmar and its neighbourhood at 2:30 pm of the Indian Standard Time (IST) today.
It is now believed by the meteorologists here that in view of this situation, maximum temperatures are most likely to shoot up over the region gradually.
It is also expected by the meteorologists that the weather condition resulted from the cyclone-induced rainfall will again lead to increase in thundershower activities over the region shortly. This is because of the availability of enough rainfall-induced moisture on the region�s surface and the impact of the subsequent rise in ambient temperatures on this quantum of moisture.
India Meteorology Department (IMD) in its �All India Weather Summary and Forecast Bulletin� issued at 4:45 pm today said rain/thundershowers observed during the past 24 hours between 8:30 am of May 4, and 8:30 am of May 5, at most places over Assam and Meghalaya, Nagaland, Manipur, Mizoram and Tripura, among others. It also stated that the places which recorded 2 cm (20 mm) or more rainfall till 8:30 am
today, included Cherrapunji - 28 cm, Shillong - 13 cm; Guwahati Airport - 8 cm; Tezpur - 6 cm; North Lakhimpur, Golaghat, Mazbat, Haflong, Goalpara and Itanagar - 5 cm each; Jorhat - 4 cm; Dibrugarh, Lumding, Silchar, Dhubri, Kohima, Kailashahar - 3 cm each and Chaparmukh - 2 cm.
Moreover, heavy to very heavy rainfall activities were observed during the above period at isolated places over Assam and Meghalaya and thunderstorms observed, from 5:30 pm yesterday to 8:30 am today, at isolated places over Nagaland- Manipur- Mizoram-Tripura Meteorological Sub-division, among others, said the IMD bulletin.
According to Regional Meteorology Centre (RMC) sources here, William Nagar in Meghalaya received 17.5 cm during the above 24 hour period between 8:30 am yesterday and 8:30 am today and Guwahati city received 10 cm of rainfall during the same period.
It needs mention here that a rainfall ranging between 64.5 mm and 115.5 mm (that is 7 cm to 11 cm) within a period of 24 hours or its part, is described in meteorological parlance as a heavy rainfall. While a rainfall ranging between 115.6 mm and 204.04 mm (12 cm to 20 cm) is described as a very heavy rainfall, a rainfall greater than or equal to 204.05 (21 cm or above) is described as an extremely heavy rainfall by the meteorological parlance. Going by these meteorological phrasing, Cherrapunji received an extremely heavy rainfall during the said period, while Shillong and Williamnagar received very heavy rainfall, Guwahati Airport and Guwahati city received heavy rainfall.
