During the Monsoon season specifically, several weather systems develop on either side of the coast. Similarly, a low pressure area was over Northeast Arabian Sea, Gulf of Cambay between Konkan and Saurashtra Coast. The system had formed on July 11 and had remained stationary for a while.
Now, the system has weakened a little but is still a strong enough Cyclonic Circulation. The system is the most prominent feature over the country which is driving rainfall across Gujarat and Maharashtra including Mumbai.
Now, we can say that the system is expected to weaken further and will become a little less marked by tomorrow. The system will diminish further day after tomorrow and probably become insignificant.
This is the only system which has caused heavy rainfall activities over the state of Gujarat and in these 24 hours. Moreover, the system will cause some rainfall activities over the Saurashtra region, that too starting with Veraval, Dwarka, Diu, Okha, Porbandar, Jamnagar along the coast.
Cities slightly away from the coast including Junagarh and Amreli may also witness some rainfall activities. However, rains will not extend far off up to the northern parts of the state including Surendranagar, Patan etc.
This low pressure area will keep the Monsoon activity on over Gujarat and coastal areas of Maharashtra along with Marathwada and Madhya Maharashtra region for another 24 to 48 hours. The remnant of the low pressure area will shift a little northward, activate the Monsoon trough and bring a heavier spell of rain over the Northern Plains of the country including the national capital, Haryana and Punjab during the weekend.
