Hyderabad: Monsoon is expected to leave the state in the next five days. The monsoon withdrawal line currently around Madhya Pradesh will reach Telangana by13 October resulting in the onset of the withdrawal of the year's monsoon from the state.
The monsoon withdrawal line is an imaginary line, the area above which experiences dry weather whereas heavy rain activities take place below the line.
"Monsoon withdrawal simply means a change in the wind pattern and rainfall," explains Sai Praneeth popularly known as Andhra Pradesh weatherman. It means that the southwest monsoon winds leave the state and the northeast monsoon winds enter.
The Meteorological Centre, Hyderabad, on Friday said thunderstorm accompanied with lightning is likely to occur at isolated places in a few districts of Telangana during the next 48 hours. Praneeth said this is because it is currently in the east-west shear zone.
The east-west shear zone is an area in between the easterly flow of wind in the north and the westerly flow of wind in the south. It is favourable to heavy rain activities and thunderstorms. "By next week, Telangana will experience lesser rains," says Praneeth.
In a bulletin, the Meteorological Centre said that the southwest monsoon has been weak in Telangana during the last 24 hours. Isolated places in the state received rains during this period.
In Andhra Pradesh, the monsoon is expected to withdraw by 20 October. The withdrawal from the state also marks its withdrawal from the entire country. By next week, the east-west shear zone is expected to move to AP causing heavy rains and thunderstorms in the state till 20 October. "Never think withdrawal means the end of rains. For AP, the real rainy season has started," tweeted the weatherman. The state will thereafter witness the onset of northeast monsoons.
