An intense thunderstorm swept across the central San Joaquin Valley on Sunday night, dropping torrents of rain and treating Valley residents to a spectacular lightning show.
As of 11 p.m., the storm had dropped 0.87 of an inch of rain in Fresno, bringing the season total to 16.66 inches, said Gary Sanger, a meteorologist with the National Weather Service in Hanford. It is the ninth rainiest season on record.
Valley agencies reported no flooding or weather-related traffic accidents, although the CHP reported flooding on a Highway 41 onramp to Highway 99. Minor street flooding was spotted at some locations in Fresno, and the National Weather Service issued a flood advisory for the central San Joaquin Valley through early this morning.
The overnight downpour pushed Fresno's 24-hour rainfall total to 1.37 inches, helping to make June the fourth wettest on record, according to the weather service. The monthly total is 1.49, putting within reach the record total of 1.93 inches, set in June 1998.
In other Valley cities, Merced recorded 0.43 of an inch, Madera 0.68, Hanford 0.69, Visalia 0.69 and Porterville 0.17.
Sanger said thunderstorms are unusual for this time of year. "Normally, spring storm season is more like April and May. This is the summer monsoon season more than spring storm season," he said.
More heavy rain is possible today, as the forecast has a 30% chance of precipitation. The rest of the week is expected to be clear with daytime temperatures reaching the 80s by Wednesday.
