Monsoon rain reaches last post

The Monsoon has finally covered west Rajasthan but the advancement has been very sluggish this year. Advancement of Monsoon in India is usually not uniform; sometimes it is quick and covers a large part of the country and at times it is slow.

Going by the trend, the western arm of the Monsoon line generally makes a quick advancement. For example, the onset date of Monsoon in Kerala is 1^st June and by 10^th June it crosses Mumbai and reaches Dahanu. The eastern arm of the Monsoon is also known for moving quickly, but they slow down after covering some distance.

The slowest advancement is over wester Rajasthan. It normally takes about 12 days for the Monsoon to reach west Rajasthan after its onset over Delhi on 29^th June. The variation remains very high and could take even longer.

The irregular advancement of Monsoon can be gauged by the fact that in 2005 the Monsoon had covered the entire country by 30^th June, while in 2006 it was delayed and covered the country by 24^th July. This clearly shows how high the variation is.

This time too Monsoon has been delayed, covering west Rajasthan by 17^th July. In a span of 24 hours, from 8.30 am on Wednesday the bordering areas of Jaisalmer received 3 mm of rain and Bikaner 3 mm. Ganganagar and Jaipur received 36 and 46 mm of rain respectively.

It is to be noted that after the arrival of Monsoon, the region observes infrequent rain.
