The intensity of rainfall (part of regular Monson) increases from the 9th of August 2011 causing flash flooding in few districts in Sindh and Punjab Provinces. In District Badin alone heavy intermittent rains played havoc prompting displacement of around 40,000 people to 86 relief camps set up in all five Tehsils. The District Government declared an emergency in District Tharparkar and District Badin to contain the situation and mobilize the provision of relief and rescue to the affected families. Currently the reports of the PakMet and FFD indicate that the rain spell over these districts of Sindh is thinning and the rain spell is focused over upper Pakistan.
Media reports indicate that the flood waters from Badin are entering the adjoining District Thatta to inundate the low lying regions. The places of coastal regions in Thatta and Badin are lower than the sea level; therefore, heavy rains combine with sea water intrusions to cause sustained flooding.
