Record breaking rainfall caused flash flooding in southern Arizona yesterday, 08 September 2014, which resulted in the deaths of two people in the Tucson area of the state.
The massive rainfall was said to be caused by the remnants of former Hurricane Norbert that hit parts of Mexico in the previous days. Heavy rain and flash flooding was also seen in parts of Nevada and southern California, causing chaos on many of the states’ roads.

Arizona
According to WMO figures, Phoenix saw 84 mm (3.3 inches) of rain fall in 24 hours to 08 September 2014. This beats the previous high of 74 mm (2.91 inches), set in 1933 This amount of rainfall in Arizona (3.3 inches) is more than the combined total normally seen in the 3 months of July, August, and September.
A woman died after her car became submerged in 10 feet of flood water in a residential area in east Tucson. Rescue teams couldn’t reach the victim in time.
A second victim drowned in her car after it was caught in flash floods in Oracle Junction, north of Tucson. A second passenger, the victim’s husband, managed to escape from the vehicle and survived.
The flash floods caused havoc on the state’s road network, in particular around the Phoenix area, where dozens of cars were trapped on Interstates 10 and 17. Later on Monday, Phoenix Mayor Greg Stanton declared a state of emergency in the city where hundreds of residents were coming to terms with water damage in their homes. Interstate 15 in north west Arizona was also affected by the flooding.
