Isolated rains in TN to continue till 18th January, MJO enters TN in February

Share

Rains have been happening at isolated places in Tamil Nadu for the past 4 days. Particularly in the Anthiyur-Varatupallam belt in Erode and Virudhunagar belt. The easterlies based convergence at isolated locations are expected to happen 2 more days till 18th January. After which whatever isolated rains happening will become even more isolated. Coastal places such as Chennai too has chance in the next 2 days to get some sudden sharp rains at isolated places.

MJO returning back to our basin in February 2022.
So for January except for the 1st 2 days, there was hardly any rains expect for some isolated spells. MJO never came into our basin in January. But in the month of January, models consistently show MJO in Phase 1/2 and Precipitation anomalies show above normal rains, so lets hope some activity will happen considering that off-season MJO has to be treated with caution as bulk of the influence will be taken by Southern Hemisphere.

These type of isolated rains will continue to happen across Tamil Nadu till 18th January.
