Marine Weather and Tide Forecast for South Monrovia Island, CA

.SHORT TERM (TDY-FRI)...14/140 PM.

A strong system for any time of year, let alone October, has finally exited the area. Still could see a 5-10 minute moderate shower just about anywhere through this afternoon but for the most part the big impacts have ended. The big rain winners were in the San Gabriel Mountains where there were several reports of rain amounts over 5". Otherwise most areas ended up with between 1 and 1.5 inches.

Going forward, really not expecting any impactful weather for several days. A light Santa Ana event will follow this storm, peaking Thu/Fri. Winds are not expected to be too strong, but could get some gusts into the 30s in the San Gabriels and some of the higher valleys of LA/Ventura Counties. The more notable change will be the temperatures which will warm up well into the 80s across the valleys and mid 70s to low 80s at the coast. May get some patches of fog tonight, especially in some of the valleys with left over moisture from the rain and rapid cooling under clearing skies. Otherwise, not expecting any marine layer formation the rest of the week so there will be plenty of sunshine.

.LONG TERM (SAT-TUE)...14/141 PM.

A switch to onshore flow on Sunday will likely bring a return to the coastal morning marine layer cloud deck. The onshore flow will also bring 3 to 5 degrees of cooling up and down the csts/vlys.

Long wave troffing will move over the area on Monday bringing more marine layer clouds and stronger onshore flow. Max temps will fall 4 to 8 locally 10 degrees and end up 6 to 12 degrees blo normals.
