Anticipated bursts of intense rain soaking Reno this week prompted a flood watch from the National Weather Service. The phenomenon, known as a pulsing storm, is caused by a monsoonal flow that works its way up from the Gulf of California and even the Gulf of Mexico. When the monsoonal flow collides with high pressure, the result is “torrential rainfall,” said Heather Richards, meteorologist with NWS Reno. The effect was first felt Wednesday night when 1.22 inches of rain fell in just one hour at the Reno airport. This overwhelmed the drainage capabilities, flooded streams and washed out some downtown streets.
