And, as per the tracking of the current low in Vagaries in the last blog, the system has moved into M.P, and heavy rains have lashed Northern M.P, with figures for Saturday's rainfall at: Gwalior 68 mms, Datia 57 mms, Khajurao 55 mms, Raipur 54 mms, Damoh 45 mms, Pendra 40 mms, Jabalpur & Umaria 39 mms each.

The rainfall activity is concentrated in the regions as per the IMD map of 19th.
It is expected now, the system will fizzle out around the M.P./East Gujarat region, by Monday. This hastening up of its demise is due to stiff resistance in the west from the stabilising anti-cyclone , forming over Pakistan /west Rajasthan.
As per the current synoptic charts, the 200 hpa jet streams are establishing themselves in the 20N-25N regions, and with strong anti-cyclone situations on the pressure chart, the humidity levels are dropping in the Western Rajasthan and adjoining regions.
Hence, it could be concluded, that the Monsoon has further widhrawn from Central Rajasthan (except the eastern parts of the state), Kutch and entire Pakistan.
