The deserts are to receive heavy rains next 2 days !
Across the border, areas of Lower Sindh will receive heavy rains from Wednesday, and Thursday Karachi will see some sharp rain showers. Some showers in the city could be heavy, as the system shows tendency to strengthen tomorrow and remain so for the next 36 hrs.

Rains will be easing off in Nepal, for a few days.
