HRRR is wishy washy about the rain as well. Not a rain front, but apparently thunderstorm conditions (ie where rain patches suddenly appear, versus the normal front moving through). This is where the models show rain in strange patches... which may occur, but you don't know where, exactly, the rain will fall. i.e. here's Oxnard with 0.65 inches per hour, but... it really depends on the exact flap of the butterfly wings.

A very long period and energetic swell will begin building in Sunday afternoon. This will bring an extreme risk for sneaker waves through Monday evening. Avoid steep beaches and climbing rocks, jetties, & outcroppings. Stay back and never turn your back on the ocean!

From Meteorologist Chad Crilley on FB: (10/29/26) Thursday FULL Forecast -Stormy Halloween in So Cal, Coastal Flood Threat Continues

A big pattern change is underway across #SoCal as we track two areas of low pressure that will bring cooler temperatures, increasing clouds, and widespread rain chances this weekend.

The first trough of low pressure will move through tonight into Friday, bringing much cooler weather and the chance for a few light showers. Rainfall amounts with this first system should be very light, with many locations seeing little to no measurable rain.

Our attention then turns to a much more moisture-rich storm system approaching Southern California on Halloween. Over the past 24 hours, forecast models have come into better agreement that the center of this low will track south of San Diego into Baja California. While this would keep the heaviest rainfall south of the border, we still expect a period of moderate to locally heavy rain across San Diego County Saturday night into Sunday morning.

HALLOWEEN TIMING: For those planning to trick-or-treat Saturday evening, scattered showers will be possible, especially later in the evening. However, the more widespread, steady rain looks to arrive around 10 PM or shortly thereafter. Rain may become heavy at times overnight before gradually tapering off during the day Sunday.

Confidence is now high that we will see measurable rainfall Saturday night. However, there is still uncertainty regarding exact rainfall totals. Even a relatively small shift in the storm's track could significantly change how much rain falls across San Diego and Imperial Counties. Right now San Diego County looks to pick up near an inch of rain, with Imperial County seeing 0.10 - 0.25"

COASTAL FLOODING UPDATE: The Coastal Flood Warning has expired and has been replaced by a Coastal Flood Advisory through 2 PM Friday. While water levels are beginning to decrease, the combination of elevated sea levels from an oceanic Kelvin wave and astronomical high tides will continue to bring minor coastal flooding to vulnerable low-lying areas. Friday's highest tides will occur around noon.

Much quieter weather is expected by Monday, with drier conditions and gradually warming temperatures heading into next week. #SanDiego #ImperialCounty #Halloween #Socalwx #Imperialcountywx #Sandiegocountywx #Elcentro #Brawley #Julian #Pinevalley #Encinitas #Oceanside

Cold, dark, but I need to run some errands, and trying to do all of them by bicycle, as many as I can. I guess I could do them in the rain on Saturday to up the challenge. 🤪 #BikeTooter #rain #CAwx
