Tracking first significant storm of the season

Mostly quiet weather is expected through Sunday. Cooler temperatures are expected this weekend. An approaching storm system will bring widespread moderate to heavy rain later Sunday night and Monday, with minor flooding, gusty winds, and cooler conditions possible. Alisal fire burn scar may see some limited debris flow. Warming and drying are expected the rest of next week.

Showers may start as early as Sunday evening along the Central Coast. Periods of moderate to heavy rain are expected to arrive just after midnight in San Luis Obispo County moving towards Ventura County in the overnight hours through midday Monday. The rest of Monday we will start to clear out with a chance of light showers. This storm does bring flooding concerns on urban roadways as well as for recent burn scars. Storm will have already exited the area by Tuesday.
