The special coverage of “widespread rainfall alert” by the Pakistan Weather Portal (PWP) is over!
-
Flash/Urban flooding
-
Two strong eastern systems
-
One strong western trough
After experiencing a dull start to the monsoon of 2011, Pakistan is all set to get proper monsoon rainfalls that it used to get every year. Some parts of Pakistan had received above average rainfall while many parts faced below average rainfall. Early this year the United Nations (U.N) had published a report that suggested that probability of floods this year are high due to lack of construction in last year’s flood-hit regions, later a report from Oxfam international also reported the same things. But this year the monsoon rainfall were not active like last year mainly due to the lack of weather systems from the Bay of Bengal. Upper Pakistan has got showers due to the interaction between western troughs and monsoon moisture where as last year it was the interaction between strong western disturbance and a strong low pressure from the Bay of Bengal that created havoc in the country and later devastating floods sank 20% land of Pakistan. Now these same conditions are erupting as a strong low pressure is in making and a strong trough of western disturbance is over Afghanistan. Will history repeat itself?
PWP upgraded its second monsoon forecast from ” very high” to “extremely high” in Sindh, PWP on July 29 forecasted monsoonal activity in Sindh in August. PWP upgrades third monsoon spell for Sindh from “moderate” to “high”, PWP forecasted the third spell on August 4. Pakistan Weather Portal (PWP) is 75% confident with this forecast after observing different meteorological factors. But we may revise our third monsoon rainfall for Sindh.

The low pressure will further intensify into a well-marked low pressure area (strong weather system) before reaching Pakistan, it will maintain its intensity for few days. The system is now likely to move in a west direction according to GFS (towards south-eastern and Upper Sindh), instead of south-eastern Sindh and coastal Sindh to Makran coast.

The upper air cyclonic circulations (UAC) over Utter Pradesh is likely to intensify into a low pressure in next 2 days (August 8 or August 9) now, it will acquire a south-west track before reaching Sindh on August 10/August 11. Certain models suggest it to intensify into depression, but it is more likely to become a low pressure or well-marked low.
Under the influence of this weather system, heavy to very heavy rainfall with strong gusty winds likely in Sindh from August 10 to August 12 night/August 13 mid-day.
Features of the weather systems
Below is the features of these weather systems (they may change as time passes by);
First low pressure
An upper air cyclonic circulations formed in the central Bay of Bengal on July 28 that moved to north-west Bay of Bengal the same day, the UAC persisted over the north-west region of the Bay for many days. On August 2, the UAC moved to northern part of Bay of Bengal but the other day it once again headed to north-west Bay. After many days of stationary movement, the UAC on August 4 crossed the Orissa coast and late that day it entered Chhattisgarh. On August 5, the UAC moved to Utter Pradesh and the other day it moved to south-east Utter Pradesh. The UAC is currently moving in south-west direction after moving in a westwards direction. The Upper air cyclonic circulations are forecasted to intensify further, it will move from Utter Pradesh to Gujarat via Rajasthan and enter Sindh by August 11 morning/evening, it will completely enter Sindh on August 12 evening. It is very likely that this UAC will start to gain intensity to become a low pressure/well-marked low pressure on its way to Sindh. Very few models had went so far in suggesting that it would become a depression over land, that is something that is extremely rare. Overall the intensity of this system will be very strong.
Trough of western disturbance
On August 4, a western trough over the Afghanistan started moving towards Pakistan slowly, on August 5 it gained intensity and moved to north-east Afghanistan. It is currently moving in westwards towards Upper Pakistan. Interaction between western trough and strong monsoon moisture will take place in coming week in Upper Pakistan as forecasted by Pakistan Weather Portal (PWP)
Second low pressure
Although it is too early to go in detail about this weather system but what PWP had observed about this system, PWP will share with its readers;
An upper air cyclonic circulations form over the Bay of Bengal and move inland on August 14 to Madya Pradesh, it will also move westwards. If it behaves as forecasted then it will bring the third spell to Sindh, if it is the opposite that no third monsoon rainfall in Sindh. Few days back, various meteorological parameters observed by the PWP showed that it will become a strong weather system (Low pressure) over Madya Pradesh and head towards South Punjab and upper Sindh. Whenever it forms or what ever track it selects, PWP will give updates.
