City’s coast remains clear of major trouble
50K evacuated in view of cyclone warning; Mum sees tree falls, house collapses with no casualties
Gorai. More than 2,000 fishermen from Colaba and 150 from Worli were evacuated to safe shelters nearby. In G-south ward alone, that covers parts of Worli and Mahalaxmi, 525 people were evacuated.
The BMC officials will now focus on removing fallen trees, electric poles on the roads, check the structural stability of several poles and trees and then continue its drive for fumigating the city for the upcoming monsoon.
In a statement issued on Wednesday, the BMC said its disaster response machinery will remain on high alert for the next few days until the cyclonic effect has passed from the city. Over 500 emergency response team members from NDRF, Mumbai Fire Brigade (MFB) and BMC were on standby.
No untoward incident was reported on all six beaches, where fire personnel and lifeguards have been on standby since Tuesday night.
IMD has also lowered the rainfall warning for Thursday to moderate. KS Hosalikar, DG of meteorology in IMD Mumbai, said, “We are lowering the rainfall warning to moderate rainfall for less than 24 hours. The cyclonic storm is still there somewhere near Pune, but it will soon settle in.”
Heavy rain, however, caused a nullah in Hanuman Nagar, Vikhroli to overflow with silt. The incident came to light when the video went viral. The video was also posted by BJP MLA Ram Kadam. Ajitkumar Ambi, assistant municipal commissioner of N ward (Ghatkopar, Vikhroli), said, “The locals dump their garbage in these drains which led to choking. We cleared it in time.”
TREE FALLS ON TRACKS One tree fall was reported between Kurla and Vidyavihar railway stations, while branches of a tree fell on railway tracks at Prabhadevi, along with a tree tilting at Mumbai Central station yard on Wednesday. The CR also stopped the toy train between Aman Lodge and Matheran. Tropical cyclones form in the tropics when the sea is warm (sea surface temperature ≥ 26.50 degrees Celsius)
When the water vapour from the warm ocean condenses to form clouds, it releases its heat into the air.
The warm air rises and is pulled into the column of clouds.
According to the IMD, the ratio of cyclones in Arabian Sea to Bay of Bengal is 1:4. However, the Arabian sea is seeing a surge in the number of cyclones — from one or two in the early years of the past decade to seven in the past two years
A pattern develops, with the wind circulating around a centre (like water going down a drain), termed tropical disturbance.
As the thunderstorm goes higher and becomes larger, the air at the top of the cloud column starts to cool and becomes unstable.
The cooling water vapour releases heat, making the air at the top of the clouds warmer, increasing the air pressure and causing winds to move outward, away from the high pressure area. This creates more thunderstorms.

Winds in the storm cloud column spin faster and faster, whipping around in a circular motion. When the winds reach between 25 and 38 mph, the storm is called a tropical depression.
When the wind speeds reach 70 kmph, the tropical depression becomes a tropical storm.
