An orange alert implies that authorities should be prepared to handle any situation arising out of severe weather conditions. Ratnagiri district, which bore the brunt of cyclonic storm Nisarga last month, is likely to receive extremely heavy rainfall at isolated places on Friday, while Raigad will receive similar downpour on Saturday, senior director of IMD Mumbai, Shubhangi Bhute, said.
As per the IMD's calculations, a rainfall between 64.5 mm and 115.5 mm in 24 hours is considered as heavy rainfall, while a downpour between 115.5 and 204.5 mm is very heavy rainfall. Rainfall above 204.5 mm in 24 hours is categorised as extremely heavy rainfall.
"An orange alert has been issued for Friday and Saturday for areas that are likely to witness heavy showers and citizens and authorities in these places will have to stay vigilant," another IMD official said.
In view of the IMD alert, Mumbai Police advised citizens not to venture out of their homes. "#HeavyRainfallAlert. The @Indiametdept has forecasted "heavy to very heavy rain at isolated places" for Fri & Sat for Mumbai.
