Low-Pressure Area Moves To Northeast Arabian Sea: Light Rains Over Gujarat Likely
Key Takeaways:
- The low-pressure area has shifted into the Northeast Arabian Sea, west of the Gulf of Kutch.
- The system is expected to weaken over the next 24 hours as it moves over colder sea surface temperatures.
- Rainfall intensity will decrease over coastal Gujarat, although light rain may persist for the next two days.
- Monsoon withdrawal from the extreme border areas of Kutch occurs around 20th September and is completed by 25th September.
- Forecast Validity: Next 8 to 10 days.

The low-pressure area over Southwest Rajasthan and adjoining South Pakistan has moved further west and now lies over the Northeast Arabian Sea, west abeam of the Gulf of Kutch. The low-pressure area is centred around 22.6°N and 66.8°E, nearly west of Okha, over the Arabian Sea. It is likely to move further away over the North Arabian Sea, keeping a safe distance from the Makran Coast. As the system enters colder waters, it is expected to weaken over the next 24 hours.

Under the influence of this system, extreme western parts of Saurashtra and Kutch received scattered moderate rainfall. Naliya in Kutch and Dwarka in Saurashtra recorded 30 mm and 29 mm of rainfall, respectively. Light rainfall was registered over other parts of the region as well. Rainfall intensity will reduce further over the coastal parts of Gujarat and places around Kori Creek, like Naliya, Punrajpur and Lakhpat.
Sea surface temperatures are reducing westward from the centre of the system. A drop in temperature of even 1°-2°C will weaken the system further. As usual, the North Arabian Sea has traditionally been colder than the rest, and weather systems do not sustain over that area. This low-pressure area will also get diffused over the sea itself.
The proximity of the system and its remnants may cause light rainfall for the next two days. The low-level winds will be slightly strong over the coastal areas of Saurashtra and Kutch.
The monsoon withdrawal period is coming closer, and the monsoon retreats from the extreme border areas of Kutch around 20th September. The withdrawal gets completed from Kutch by 25th September.
