Heavy rain alert 22Aug2014 : more rain due

Excerpt from IMetD All India Weather Bulletin of Thursday (21Aug2014 - night) Meteorological Analysis (based on 1730 hours IST)
- The axis of monsoon trough at mean sea level continues to run close to the foothills
of Himalayas.
- The trough extends from Sub-Himalayan West Bengal and Sikkim to northeast Bay
of Bengal across Bangladesh between 2.1 and 4.5 km above mean sea level persists                           
All this, in short means, is that a band of low pressure is almost stationary over the Darjeeling - Sikkim Himalaya and is resulting in continuous moisture feed to this area - which means more heavy rain in this region. 
The clouding in the IR satellite imagery of 0500h IST is consistent with this and at 0630h (22Aug2014) it is raining  cats and dogs here in Kalimpong.

Praful Rao,
Dist Darjeeling
