The autumn storm expected today could pack more rain than typically falls in San Luis Obispo for the entire month of October.

The city’s rainfall average for the month is nine-tenths of an inch, according to official records kept at Cal Poly.

John Lindsey, who has more than 20 years of forecasting weather in San Luis Obispo County, said today’s storm could bring up to an inch of rain to San Luis Obispo.

South-facing mountains, such as the peaks between Morro Bay and Atascadero, could get up to 2 inches, he said.

While rainfall will be heavy at times, Lindsey said the storm should move through the area quickly.

“It will produce moderate to heavy rain, but for a fairly short period of time,” he said.

Lindsey, a community relations specialist with PG&E, said the storm’s front edge should move through around 10 a.m.

Highs today will be in the 60s across the county, and winds could gust up to 30 mph. There will be a chance of thunderstorms into the evening. Lows tonight will be in the 50s.

Thursday will have scattered showers and similar temperatures. Friday will see drier conditions and sunny skies. Clear fall weather is expected to return this weekend, with highs in the 70s and 80s.

Getting a strong storm this early in autumn is not unusual, Lindsey said.

On Oct. 7, 2010, a storm dumped three-quarters of an inch on San Luis Obispo.

In 2009, one of the most intense October storms recorded locally brought heavy rains. On Oct. 13 of that year, Cambria received 3.66 inches; many weather stations in San Luis Obispo recorded more than 4 inches; and one spot off Highway 41 between Morro Bay and Atascadero measured 9.25 inches.
