Moisture-laden southwesterly winds from the Arabian Sea have started colliding with the Western Ghats where they rise against these ghats and cool down. The sharp drop in winds temperature brings forth fair amount of rainfall that continues for hours due to continuous flow of moisture feed from the Arabian Sea. Such conditions would prevail in Kerala, coastal Karnataka, Konkan, Goa and south Maharashtra. Heavy rain is expected at one or two places in these areas during the next 48 hours.
The other areas where monsoon is expected to reach during the next two days are entire Tamil Nadu, some more parts of Karnataka and south Andhra Pradesh. Rain is expected at a few places in these areas during the next 48 hours. South Madhya Maharashtra is also expected to get rain at one or two places.
There are chances of rain in central India at one or two places during the next two days due to a corridor of low pressure that runs from north Rajasthan and Punjab to Telangana in south Andhra Pradesh. Owing to southeasterly winds, moisture levels in the region would be high. Chances of rain in these areas would reduce after this period. Temperatures will again increase in these areas once winds begin to blow from west and southwest direction.
Monsoon will also spread to some more parts of northeast states during the next two days. Rain is likely to increase in this period. Southeasterly winds will also prevail over Uttar Pradesh, northeast Madhya Pradesh, some parts of Bihar, Jharkhand, West Bengal and Sikkim. West Bengal and Sikkim are likely to receive more rain during the period.
Temperature in Delhi has been lower than the average for past two days but now a rise is expected due to change in wind direction. Wind conditions in Delhi will be westerly to southwesterly after the next 24 hours. Drop in humidity level will bring some reprieve from sweating conditions in the capital. Day temperature could again enter in the forties during the period.
