Extreme event in the Darjeeling Himalayas as it unfurls :14Jul2019

We, in the Darjeeling Himalayas have over the past 9 days been witnessing an extraordinary weather event.
a. A low pressure area between the states of UP and Bihar resulted in a sudden spurt in monsoon activity in the region with rainfall suddenly jumping from - 56% in the beginning of Jul2019
to where we received more than our monthly average of rain for July (average 615.8mm) in the spate of just 10 days.

b. This extreme weather event is still ongoing (see below)

and IMetD has clamped on a RED weather warning for this region for an unprecedented number of days in a row.
In keeping with the enhanced rain, we have had a quantum increase in landslide activity in the Darjeeling Himalayas:
  -    We have had 2 fatalities due to landslides directly and another 4 when a vehicle carrying tourists plunged into the Teesta river on National Highway (NH)10. NH31A also had landslides in July2019.
  -   NH10, an arterial road connecting Sikkim to the rest of the country has been blocked for the past 2 days and so have virtually all the roads out of Kalimpong towards Sikkim and the Dooars plains. NH55 which links Darjeeling to Siliguri is cut off at places and the services of the DHR have been suspended.
 -   There have been a spate of landslides all over the districts of Kalimpong and Darjeeling. We will be giving more details on the landslides in this blog.
