As Temperatures Increase, So Does Wildfire Risk

Ramona should be cautious of wildfires due to the hot temperatures and gusty winds Friday.

Hot, dry weather is expected in San Diego County Friday and this weekend, creating some risk of wildfire, according to the National Weather Service (NWS).

The NWS said temperatures could be 15 to 20 degrees higher than average in coastal and valley areas today and especially Saturday, when no marine layer whatsoever is expected.

Temperatures in the 80s are expected at the beaches, up to 98 degrees a few miles inland, up to 104 degrees in the valleys and up to 106 degrees in the deserts. Overnight temperatures should drop back into the high 60s and 70s, according to NWS forecasters.

With humidity levels relatively low, the heat index that gauges how hot it really feels will not reach critical values, according to the NWS. But the conditions will create a heightened risk of fire.

"There will be an elevated wildfire risk over the foothills and adjacent valleys in San Diego County," where the vegetation is dry "and local gusts of 25 to 35 miles per hour from the east are expected, mainly during the mid to late morning," according to an NWS advisory.

The NWS advised those planning to be outdoors to stay hydrated and avoid strenuous activity during the hottest part of the day.

"Cooling will begin on Sunday and continue through early next week as high pressure aloft weakens and onshore flow increases," the advisory said.

Anybody with a brain, especially a weather station would know better than to believe the temperature would drop into the 60s when the daytime temps are triple digits. At 4:30am our personal weather station said the temperature was 84° compared to NOAA stating it was 71°. I suppose that's better than the stupid God awful Weather Channel that said it was 61° at that hour and with a iumidity of 52%, when it was actually 15%. I wish these weather stations folks would get their heads out of the sand, office or wherever they are and really take a look outside.

Interesting.It's Sunday. North of town it's in the high 70s, low 80s at 5am with a humidity of 23%. That's some major difference within only 5 or 10 miles.
