Thunderstorm raids East Coastline

In simple fact, Saturday and Sunday saw a uncommon but hazardous thunderstorm raiding the East Coastline from Andhra Pradesh, Telangana, Tamil Nadu and Karnataka in a South-South-West path manufacturing substantial lightning strikes and moderate to large rainfall across the location.

In a lot of circumstances, convection-induced winds just take on a bow echo (backward ‘C’) sort of squall line, normally forming in a location abounding in prosperous reduced-amount dampness (from the Bay of Bengal) and heat-air advection (horizontal motion).

On extremely uncommon occasions, tornadoes could accompany the thunderstorms, lightning, and hail. Traveling through these winds can be extremely hazardous.
