At least one million people were affected by seasonal monsoon rains in southern Pakistan. Heavy rains, which began in July, caused 162 deaths in Pakistan as of August 3, with 153 of the fatalities in the Sindh province (AFP). More than half a million houses had been damaged or washed away in an area more than 1,000 square kilometers (400 square miles) in size. In Nepal, floods from monsoon rains had claimed 205 lives and destroyed over 3,000 houses (OCHA).
In the United States, thunderstorms on the 19th brought some of the heaviest rainfall and flooding to the Las Vegas, Nevada area since 1999. As much as 75 mm (3 inches) of rain fell in parts of the area in just 30 minutes, producing widespread flooding and prompting the mayor to declare a state of emergency (Las Vegas Sun).
In China, at least 86 people were killed and $700 million reported in losses (Reuters) due to flooding, landslides and Typhoon Dujuan in August and early September. Twelve days of heavy rain in the northern province of Shaanxi led to some of the worst flooding in 40 years for the region. Approximately 4.9 million people were affected by the flooding (Reuters). Details of Typhoon Dujuan can be be found below.

A cold frontal passage signaled the end of the heat wave for much of Europe, although strong thunderstorms associated with the front brought severe weather to parts of southern France and Spain. The storms produced flooding and scattered power outages as they affected the region on the 17th. |
