A little appetizer rain has been recorded around San Diego County. San Diego has since added another 0.02 of an inch. The strongest gust recorded at San Diego International has been 32 mph at 10:44 a.m. The bulk of the rain is still expected late tonight & Sunday morning. #sandiegoweather #CAwx

Here are the National Weather Service's three possible scenarios with Rachel: #sandiegoweather #CAwx #Rachel

Haven't been able to say this for many months this hot year: If you live in S.D. County & have automatic sprinklers, you can turn them off & leave 'em off for a week or more. The bulk of the rain should fall tonight & early Sunday, but it should be moist & cool into Tuesday. #sandiegoweather #CAwx

Here's how much rain the weather service predicts for various communities between about noon today and early Tuesday: Oceanside, 1.15 inches; San Diego, 1.27; Chula Vista, 1.33; Fallbrook, 1.22; La Mesa, 1.38; Palomar Mountain, 2.26; Mount Laguna, 1.81; Borrego Springs, 0.65. #sandiegoweather #CAwx

Rachel bears a slight resemblance to Hilary, which dropped 1.84 inches of rain on San Diego on Aug. 20-21, 2023. At its peak, Hilary was a much stronger storm. I wrote about Hilary for Voice of San Diego as it approached: voiceofsandiego.org/2023/08/18/w... #sandiegoweather #CAwx

As Rachel gets closer, the rainfall projections from the National Weather Service are rising. San Diego could get 1.5 inches of rain on Sunday alone. Palomar Mountain could get 2.5 inches. Then more is likely Monday and Tuesday from a separate storm from the north. #sandiegoweather #CAwx

Latest look at Rachel, lurking to San Diego's southwest. The tropical storm will approach the region Saturday night. From the weather service: A continued northern shift would
increase potential for heavy rain across the county with a southern shift making it more localized. #sandiegoweather #CAwx

Didn't know whether to use "it's not too often you see" or "I can't recall seeing." Going with: "This is a first for me." It's a warning & watches map with a coastal flood warning, a tropical storm watch, a flood watch AND an extreme heat warning. All in Southern California. #sandiegoweather #CAwx

It's possible that some spots in San Diego County will experience tropical-storm-force winds from what's left of Rachel, but the National Hurricane Center's current map shows the odds are very slim. #CAwx #sandiegoweather

Real rain? Rachel (right) is struggling to keep itself together, but the National Hurricane Center expects it to be a strong tropical storm at landfall, likely near the U.S.-Mexico border. Rainfall projections include totals from a separate storm from the north Mon. & Tues. #sandiegoweather #CAwx

S.D. County is now under a tropical storm watch. The National Hurricane Center moved the probability cone back to the north. So far, winds west of the mountains will likely not top 30 mph. Mountains could get 40 mph gusts. Rainfall Sunday to Tuesday estimated at 0.7 to 1 inch. #sandiegoweather #CAwx

In 2025, San Diego never hit 90°. This year, it has hit at least 93° 9 times: 4 times in Sept., 5 times this month. It just missed Wednesday, with a high of 89.
Hottest days this year:
Oct. 3: 105
Oct. 4: 100
Oct. 5: 97
Sept. 6 & 7, Oct. 2: 95
Sept. 9: 94
Sept. 8, Oct. 6: 93

San Diego is now outside the National Hurricane Center's latest warning cone for Tropical Storm Rachel. That doesn't mean the city won't feel impacts. Heavy rain is still possible with the current projected track, but if Rachel veers a little north, impacts could be greater. #sandiegoweather #CAwx

San Diego is now on the edge of the National Hurricane Center's warning cone for Tropical Storm Rachel. But the center notes: "Hazardous conditions can occur outside of the cone." The weather service says Rachel, combined with high tides, could cause some coastal flooding. #sandiegoweather #CAwx

The weather service has a harder time predicting weather coming up from the southwest, like Tropical Storm Rachel. There aren't many prior examples, nor weather stations down there. But forecasters are increasingly confident S.D. County will get soaked starting late Saturday. #sandiegoweather #CAwx

It’s a beautiful, warm night for playoff baseball at Petco. 81 degrees, clear and no wind, other than the breeze created by the rally towels. #Padres #CAwx #sandiegoweather

One more scorcher? The weather service expects San Diego to hit 91 today for the 6th straight day. Thursday's high is forecast to be "only" 89 - still 14 degrees above normal. If the city hits 91 today, it would tie the daily record high set in 1951. #sandiegoweather #CAwx

San Diego reached 93° today - not a daily record. But several other spots in the county did set or tie records. Not setting records today but still very hot: Poway, 106; Santee, 105; Fallbrook, 103; Valley Center, 102; Rancho Bernardo, La Mesa, 101; Lemon Grove, 100. #sandiegoweather #CAwx

San Diego's official weather station at the airport has hit 92°. It's the fifth straight day of 92 or hotter. The weather service expects Wednesday to reach 90. Normal high this time of year is 75. Besides blazing afternoons, the nights are setting records for highest minimum. #sandiegoweather #CAwx

Yet another record-setting day in San Diego County. For the city of San Diego, it's the 4th straight day that set or tied a daily high record. With highs in the 90s expected Tuesday & Wednesday, this could go down as the city's hottest first week of October in its history. #sandiegoweather #CAwx
