‘When thunder roars, go indoors.’ SLO County meteorologist warns of storm
In a post on X, meteorologist John Lindsey described the upcoming storm as a 548-decameter upper-level low-pressure system spinning counterclockwise around 250 miles west of San Luis Obispo.
In the post, Lindsey said the storm will move southeastward into the Southern California Bight later today, producing convective rain showers and a chance of thunderstorms through Thursday morning.
Lindsey said the heaviest rain is expected this afternoon, with rainfall totals ranging between 0.25 and 1.5 inches throughout the region.
“As a precaution, heed the advice of the National Weather Service: ‘When Thunder Roars Go Indoors,’” Lindsey said in the post. “Stay safe and prepared for changing weather conditions.”
I woke up this morning to this view from our back window, and no wonder, a 548-decameter upper-level low-pressure system is spinning counterclockwise about 250 miles to the west of San Luis Obispo and will move southeastward into the Southern California Bight later today.… pic.twitter.com/fx22FLht03
