00:00The monsoon has already covered the whole of India.
00:05You have seen the news recently.
00:07There is a seismic zone in Bangladesh and its adjoining areas.
00:14Its centre is in Bangladesh.
00:16The seismic zone is 7.6 km from the coast.
00:24The seismic zone is tilting southward.
00:28The seismic zone is 7.6 km from the coast.
00:33As of today, it is difficult to say.
00:37It is not possible to say.
00:39The seismic zone may descend to the coast after 24-48 hours.
00:47It may cause a low pressure.
00:49But it will happen.
00:51We are not in a position to say.
00:53But we cannot ignore this possibility.
00:56It has happened many times in monsoon season.
00:59We call it in-situ development.
01:02There is a cyclonic circulation.
01:04It happened 2-4 days ago.
01:07It was like that.
01:09There was a cyclonic circulation.
01:11You said that it may happen after 24-48 hours.
01:16After 24 hours, it has descended to the surface.
01:21It works as a mechanism.
01:24In scientific language, it is called vortex stretching.
01:28Have you seen a dot pen spring?
01:32Imagine that you have a spring.
01:34You pull the lower portion of the spring.
01:38You pull it so that there is no movement in the spring.
01:42We call it stretching.
01:46What happens in this mechanism?
01:48There is a cyclonic circulation.
01:50It extends from one level to another.
01:54It stretches to the surface.
01:57When it reaches the surface, it is already low pressure.
02:02We are not in a position to say.
02:09But we cannot ignore this possibility.
02:13It has happened many times.
02:15Let's see what happens in the next 24-48 hours.
02:20This is one synoptic situation.
02:22It is important for our region.
02:24There is another one.
02:26In 0.9 km from Samudra Prishto,
02:30there is a spring in Jharkhand.
02:33From that spring,
02:35an east-west oriented trough
02:38in 0.9 km
02:41reaches Manipur.
02:43When it reaches Manipur,
02:45it passes through Gangetic West Bengal.
02:48It passes through Murshidabad.
02:52As a result,
02:54in the southern and northern parts,
02:58there is a possibility of widespread rainfall.
03:05In the northern parts,
03:07as usual,

03:30is likely to receive rainfall.
