Mumbai: As heavy rain continued to lash Maharashtra, the Regional Meteorological Centre of the India Meteorological Department (IMD) issued a ‘red alert’ for Mumbai. Earlier, the office had sounded an ‘orange alert’, but it is now been changed to ‘red alert’ for Wednesday because of the “favourable synoptic conditions”, Jayant Sarkar, head of the Regional Meteorological Centre said.
Extremely heavy rainfall means precipitation of more than 204.5 mm in 24 hours, the met office said. The IMD describes rainfall as ‘very likely’ when the probability of the occurrence is 51 to 75 per cent.
A red rain alert also means authorities should take preventive actions such as the evacuation of people from vulnerable areas and deploy rescue teams.
According to the forecast issued by the Regional Meteorological Centre Mumbai, the city is likely to get moderate to heavy showers in a few areas. The IMD also predicted intense rainfall activity over entire north India from July 18-21 and over the west coast till July 23 where places like Konkan and Goa have received a red alert indicating the probability of extremely high rainfall.
Alerts by the IMD are colour-coded from green to red. A ‘green’ alert stands for “no warning” and no action needs to be taken by the authorities, and the forecast is of light to moderate rain. A ‘red’ alert stands for “warning”, and asks authorities to “take action”. An ‘orange’ alert indicates that the authorities are expected to “be prepared”.
