Rare rain storm swept through SLO County over the weekend. Here’s how much your area got
Parts of San Luis Obispo County saw thunderstorms, lightning and rain over the weekend as a tropical storm hit Southern California.
Rainfall is rare in September on the Central Coast.
SLO County typically only sees about 0.04 to 0.06 inches of rain for the entire month, according to the National Weather Service.
The wet weather followed a heat wave that brought triple-digit temperatures to the region.
Although some areas only saw sprinkles, receiving enough rain to wet the ground for a few hours, other Central Coast spots experienced more dramatic weather.
On Friday, Morro Bay High School was forced to call its football game against Fresno due to lightning.
Meanwhile, heavy rainfall resulted in flooding at Highway 33 near Cuyama in Santa Barbara County on Sunday.
Meteorologist John Lindsey predicted that the ridge of high pressure responsible for the recent heat will move toward the east this week — bringing lower temperatures and strong to gale-force northwesterly (onshore) winds.
The cooling trend was forecast to start Tuesday and continue through next Sunday, Lindsey said.
