Thursday, August 4: While the northern and northwestern parts of the country have made a wet start to August, the monsoon activity over the regions is now set to intensify, with heavy showers on their horizons for the latter half of this week.

As per the India Meteorological Department (IMD), fairly widespread to widespread rains, thunderstorms and lightning are very likely over Himachal Pradesh, Uttarakhand, Uttar Pradesh, Punjab, Haryana, Chandigarh, Delhi and East Rajasthan during the next five days — from Thursday to next Monday, August 4-8.

Isolated heavy falls (64.5 mm-115.5 mm) may lash West Uttar Pradesh, Uttarakhand and East Rajasthan from Thursday to Sunday (August 4-7), Himachal Pradesh from Friday to Monday (August 5-8), and West Rajasthan on Sunday and Monday (August 7-8).

Furthermore, isolated very heavy rains (115.5 mm-204 mm) have been forecast over Uttarakhand for the next 24 hours and across East Rajasthan from Saturday to Monday (August 6-8).

Accordingly, both Uttarakhand and East Rajasthan will be placed on an orange alert (‘be prepared’ for rough weather) for the aforementioned time frames. The rest of the states and UTs will remain on a yellow watch (‘be aware’ of local weather situation) during this five-day forecast period.

This spike in rainfall activity will be caused by the monsoon trough and multiple embedded cyclonic circulations, and the heavy rains’ impact will be most notable along the northern edge of the trough, The Weather Channel’s met team has indicated.

In fact, this fresh rain spell started impacting North and Northwest India from Wednesday (August 3) onwards. In the past 24 hours, the IMD has observed rainfall and thunderstorms at a few places in East Uttar Pradesh and at isolated locations in Himachal Pradesh, Uttarakhand, Punjab, Haryana, Chandigarh, Delhi, West Uttar Pradesh and Rajasthan.

As far as the seasonal precipitation is concerned, the rainfall activity across the region has varied so far this monsoon. Between June 1 and August 3, the states and UTs in the region have recorded the following rain figures:

Excess rainfall: Rajasthan (337.7 mm), Haryana (267.6 mm)

Normal rainfall: Uttarakhand (561.7 mm), Himachal (355.1 mm), Punjab (277 mm), Delhi (242.3 mm)

Deficit rainfall: Uttar Pradesh (209.1 mm)
