Rain and Thunderstorms Forecast Across Andhra Pradesh and Telangana
The low pressure that was formed in the southwest Bay of Bengal near Tamil Nadu coast continues in the same location as of 08:30 AM on October 21. Another cyclonic circulation formed over Gulf of Thailand and the nearby areas of Thailand and Myanmar and persists as of 08:30 AM on October 21 extending up to 5.8 km above the mean sea level. This cyclonic circulation is likely to move into the northern Andaman Sea today, October 21, and then move west-northwest. A low pressure is likely to form around October 23, 2026, over the southeast Bay of Bengal and the adjoining east central Bay of Bengal.
It is then likely to move northwest and intensify further over the next three days. A trough that was formed earlier from the low pressure belt near the Tamil Nadu coast through the southwest Bay of Bengal towards the north coastal Andhra Pradesh at 3.1 km above the mean sea level has weakened. The Meteorological Department has issued weather forecasts for Andhra Pradesh and Telangana for the next three days. Rainfall Expected For Three Days Light or moderate rain or thundershowers are likely to occur at a few places in Coastal Andhra Pradesh, Yanam, and Rayalaseema over the next three days. Heavy rainfall is expected at one or two places, and thunderstorms with lightning are also likely to occur at a few places. The Amaravati center has forecast that wind speeds gusting at 30-40 kmph with occasional gusts up to 50 kmph are likely.
Under the influence of a cyclonic circulation over the southwest Bay of Bengal and the adjoining Tamil Nadu coast, a low-pressure area formed in the same region at 05:30 AM today (October 21, 2026). As of 08:30 AM today, the system persists in the same area. The associated cyclonic circulation extends up to 5.8 km above mean sea level. A trough that previously extended from the low-pressure area over the southwest Bay of Bengal and the adjoining Tamil Nadu coast toward North Coastal Andhra Pradesh—at an altitude of 3.1 km above mean sea level—has weakened. Meanwhile, a cyclonic circulation over the Gulf of Thailand and the adjacent regions of Thailand and Myanmar continues to persist, extending up to 5.8 km above mean sea level as of 08:30 AM today, October 21. It is likely to enter the northern Andaman Sea by today, October 21.
Subsequently, it will move in a west-northwesterly direction. Under its influence, a low-pressure area is expected to form over the southeastern and the adjoining east-central Bay of Bengal by October 23, 2024. Following this, it is likely to move in a northwesterly direction and intensify further over the next three days. The Hyderabad Meteorological Centre has forecast rain in Telangana over the next three days due to these developments. Today, light to moderate rain is expected in some parts of Telangana, while dry weather is likely to prevail over the next two days. The Hyderabad Meteorological Centre has also predicted that some areas in the state may experience rain accompanied by thunderstorms, lightning, and gusty winds blowing at speeds of 30–40 kmph today.
