The arrival of the remnant low near Mumbai, has brought very heavy rains in South Konkan and Goa. On Sunday/Monday, Rajapur (S.Konkan) received 210 mms of heavy rains, and Harnai got 92 mms. Several palces in Goa recorded between 5-7 cms rain.
Due to prevailing moisture, Madhya Mah.regions will see thunder cells popping up in isolated patches for the next 2 days. Konkan rains will return on Wednesday 20th./Thursday 21st.
Mumbai city received light to medium thundershowers, of varying intensities in different areas, on Monday evening and into the night.
The remnant low over Mumbai decreased from 1004 mb to 1006 mb by Monday evening.
But it was enough to garner up moisture and precipitate rains along the North Konkan/South gujarat coast on Monday.
Though I expect the low to be temporary, and fizzle out by Tuesday, we see another pulse aloft, at 700 hpa tracking west and settling over south Konkan
by Wednesday 20th./Thursday,21st. October. Simultaneously, on the 21st. as per IMD/GFS forecast, we see a trough dipping into the North Arabian Sea region.
Mumbai can expect some rainfall on Thursday 21st. Oct.
