At 8:30 AM IST on February 19, a low-pressure system continued to linger over the Equatorial Indian Ocean and the nearby southwest Bay of Bengal. The system is predicted to proceed west-northwest toward Sri Lanka and progressively diminish over the course of the following day, per the most recent meteorological update.
Most Likely to Form a New System
Meteorologists have predicted the creation of a new weather system even as the current low pressure system waned. As of 8:30 AM IST on February 19, an upper-air cyclonic circulation has formed over the Equatorial Indian Ocean and the nearby southeast Bay of Bengal, reaching the middle troposphere.

Within the next 24 hours, a new low-pressure area is probably going to form over the same area due to its effect. After that, this storm is predicted to move west-northwest, which could have an impact on the weather across the southern regions of the nation and the nearby oceans.
Furthermore, there is currently a trough in the lower tropospheric levels that stretches from the Lakshadweep region to the cyclonic circulation connected to the current low-pressure area. Over the Indian peninsula, this trough is probably going to increase convection and moisture intrusion.
