The Indian Meteorological Department (IMD) in Hyderabad said that thunderstorm accompanied with gusty winds are likely to occur in isolated places in all districts of Telangana on Monday.
Issuing a two-day warning, the IMD also said that light to moderate rain was very likely to occur at a few places across the state.
According to reports, the thunderstorm was the result of a cyclonic circulation over north Maharashtra, adjoining Vidharbha and southwest Madhya Pradesh, and extending up to 1.5 km above the mean sea level.
The IMD also said that a cyclonic circulation lies over south Karnataka at 0.9 km above the mean sea level.
Earlier this week, heavy rainfall and thunderstorms which lashed the city for at least two hours on Friday, brought Hyderabad to a standstill. Many trees were uprooted and there were power disruptions reported at several places.
The Greater Hyderabad Municipal Corporation (GHMC) later said that 69 trees had been uprooted, out of which 24 trees were uprooted in the North Zone, 14 in the West Zone, 21 in the Central and 10 in South Zone.
The city recorded the maximum rainfall of 52.5mm (5cm) in Khairtabad followed by Nampally at 38.5mm (3cm).
Rains lashed from 8pm to 10pm leading to traffic jams in several areas.
According to Indian Meteorological Department (IMD), Saidabad and Asmanghad received 32mm of rain, Khairatabadâ€™s Srinagarcolony 31.3mm, while Ameerpet and Maitrivanam got 26.5mm.
Hailstorms were also reported in parts of Secunderabad like Trimulgherry, Yapral and Bowenpally
The IMD scientists stated that the reason for the unseasonal rainfall was cumulonimbus clouds.
Cumulonimbus clouds are commonly known as thunderclouds that can produce hail, thunder and lightning. They are born through convection often growing from small cumulus clouds over a hot surface, and also form along cold fronts as a result of forced convection, where milder air is forced to rise over the incoming cold air.
