SYNOPSIS

19/910 AM.

A cooling trend will begin today and continue through mid week as a storm approaches. Light to moderate rain is expected late Monday into Tuesday, focused over San Luis Obispo County with minimal impacts. Widespread gusty west to northwest winds will follow Wednesday through Friday.

LONG TERM (WED-SAT)

19/336 AM.

The low pressure system is likely to exit the region Wednesay into Thursday, though there will remain a slight chance of showers, particularly along north facing mountains slopes. West to northwestern winds are likely after the passage of the front, with gusty conditions expected across the beaches, mountains, and deserts. Winds will then become northwesterly later Thursday and Friday as a weak inside slider noses into the region, with winds focused over the more typically windy mountain/desert areas.

Cool temperatures will continue on Wednesday (widespread 60s), increasing to near normal by the end of the week. Additional light rain is again possible sometime between next weekend and early next week (4/25-4/28), as some models have the inside slider system traveling westward and centering over the coastal waters.

MARINE

19/338 AM.

High confidence in winds and seas remaining below Small Craft Advisory (SCA) levels through tonight. A system will move through the coastal waters Monday afternoon through Wednesday morning bringing a chance of showers to much of the area. Cannot rule out a thunderstorm or two across the northern waters Tuesday morning.

SCA level southerly winds are possible along the cold front. By Wednesday afternoon into the evening hours, SCA level NW winds will develop south of Point Conception. These winds will likely expand to include the majority of waters by Thursday afternoon. SCA winds may persist into the weekend at least for some waters.
