With only 23 days till the southwest monsoon season ends, bloggers predicted that the state would have one of its wettest monsoon seasons ever.
IMD has predicted thunderstorms with mild to moderate rainfall over some locations of the state over the ensuing 48 hours, with partly overcast skies also likely.
Maximum and minimum temperatures may be in the range of 34-35°C and 26-27°C, respectively.
