The potential for rain is expected to increase from Saturday into Sunday as tropical moisture moves northward, though forecasters said considerable uncertainty remains over where the moisture will concentrate.
There is also a 10% to 15% chance of moderate to strong easterly winds developing ahead of the rain, potentially creating fire-weather concerns.
High Surf Likely
The greater concern heading into the holiday weekend is along the coast.
A south-to-southeast swell generated by Marie is expected to increase surf across Southern California beaches during the weekend. The largest surf is expected from Oceanside northward, according to the NWS.
Swells from Hurricane Karina, which dissipated at the end of August, are also expected to remain in the region.
