The cyclonic circulation over the southeast Bay of Bengal has moved west-northwest and now lies over the southeast Bay of Bengal. Under its influence, a low-pressure area is expected to form over the central parts of the south Bay of Bengal around October 14, according to the Meteorological Centre.
The daily weather report indicates that this low-pressure area is likely to become well-marked and move west-northwest towards the south Andhra Pradesh coast in the next 48 hours.
Heavy to very heavy rainfall is expected in isolated areas of Rayalaseema on October 15, 16, and 17, as well as in South Coastal Andhra Pradesh on October 15 and 16.
Heavy rains are predicted to continue in South Coastal Andhra Pradesh over the next 48 hours, in Rayalaseema on October 14, and in North Coastal Andhra Pradesh and Yanam on October 17. Thunderstorms with lightning are expected in isolated places across North Coastal Andhra Pradesh, South Coastal Andhra Pradesh, and Rayalaseema over the next five days.
Light to moderate rainfall or thundershowers are likely at most places, or one or two locations, in North Coastal Andhra Pradesh, South Coastal Andhra Pradesh, and Rayalaseema during the next week. Rainfall has already occurred in a few areas of Coastal Andhra Pradesh and one or two places in Rayalaseema over the last 24 hours.
The upper air cyclonic circulation over the southwest Bay of Bengal now lies over north interior Tamil Nadu, extending up to 3.1 km above mean sea level and tilting southwest with height. A trough extends from the centre of the well-marked low-pressure area over the east-central and adjoining west-central Arabian Sea to the Comorin area across south Kerala, along with a cyclonic circulation over Tamil Nadu between 3.1 km and 5.8 km above mean sea level.

Meanwhile, the Andhra Pradesh Disaster Management Authority (APDMA) has warned of heavy rains on Wednesday and Thursday in Bapatla, Nellore, Prakasam, Kurnool, and Nandyal districts due to the low pressure. APDMA MD Ronanki Kurmanath stated that heavy rainfall is also expected in Nellore, YSR, Annamayya, Chittoor, and Tirupati districts.

Fishermen are advised not to venture into the sea for fishing. Moderate rainfall is anticipated for Visakhapatnam, Anakapalli, Kakinada, and Konaseema districts. The DMA has cautioned the public to avoid standing under hoardings, trees, and electric poles during the rains, as lightning is also predicted.
