Another atmospheric river storm headed to SLO County

March 20, 2023


Another atmospheric river storm is expected to bring high winds and soaking rains to San Luis Obispo County, which could result in flooding, mud slides and downed trees.

The latest storm is forecast to push through the Central Coast Monday evening through Wednesday afternoon. The storm is expected to bring strong winds of 35 to 45 mph, with wind gusts of up to 70 mph, from Tuesday morning through Tuesday evening.

“Damaging winds could blow down large objects such as trees and power lines,” according to the National Weather Service. “Power outages are possible. Travel could be difficult, especially for high profile vehicles.”

Expect rainfall totals of between 1 1/2 inches to 2 1/2 inches. Heavy rains and runoff could result in flooding of creeks, streams, and urban areas.

Not really the same as the more recent storms which were entraining moisture from the subtropics. This is going to have much lighter levels of rainfall. The low is centered right now, as I type, over the Bay Area and drawing moisture from the Pacific Northwest. Much colder. The jet stream winds are actually going south west, towards Hawaii, not towards the US west coast as was the case in the heavy rain makers. But hey, if the narrative keeps people worried, then run with it. Thankfully there will be no “Blood Moon”, “King Tides” or “Killer Hornets” involved.

Okay that’s enough….
