Hurricane in SoCal going north

Why would you worry about that? Have you checked the weather forecasts for the Bay Area? There's no sign of a tropical storm report. Do you know how hurricanes/tropical storms work? The CA coast isn't the Gulf of Mexico. Hurricanes coming up from Mexico usually dissipate by the time they reach the Bay Area, and at most will provide some moderate rain. Also Andy's post has some insight; high-pressure zones over the Bay Area tend to deflect rain, but that does not seem to be the case during El Nino years.

What causes flooding is the atmospheric rivers that come in from the central Pacific during El Nino Years. That's what you should be watching, rather than hurricane reports. Go on NOAA's website to learn about the ENSO: El Nino-Southern Oscillation. It affects weather all over the Western States and beyond. This will help you understand weather patterns on the West Coast over a period of years.

I thought your comment was directed to me. Half blind; need new glasses.

I thought why not ask even though it feels silly: don’t you think in spring, It’ll be dry enough to visit Bay Area like sf and Oakland? Mind you what’s the flooding risk in Modesto and Bay Area?

Its interesting how the permanent high pressure system in the great basin just east of California usually pushes any Tropical systems which track north of Baja California towards the west and zaps much of the moisture in it as well. This seems much more of an overlooked factor more than the water temperatures off shore, keeping systems away not just weaken it. As if conditions are right hurricanes had survived waters at that temperatures in the past even north of Los Angeles in the eastern pacific but staying well off shore. Cooler waters can weaken storms but it would still pack quite a punch if it made landfall if it wasn't for that high pressure system, which also keeps arctic blasts away as well.

Also hurricanes like Ida shown that even thousands of miles after making landfall can still be quite a punch if there isn't much to dry the low pressure system out.
In 1997 the entire west coast panicked as Hurricane Linda was poised to travel the same route as Hurricane Kay but up the entire length of the west coast after making landfall in SoCal. Meaning widespread flooding and mudslides statewide or even in the Pacific Northwest states. What happened with a abnormally strong trough pushed the high east allowing the hurricane to creep up along the baja coast towards CA and poised to hit LA at category one as the ocean water was pretty warm that year. But the trough weakened and allowed the high pressure to strengnth and steered Linda off shore thus a bullet was dodged I heard.

I am surprised though as normally if Hurricanes come to CA as a tropical depression there is usually a all night light show with downpours but it didn't materalize t his time.

Storm was a dud in San Diego. OC and LA even less.

24 hour rainfall totals along the coast topped out at .65" at the airport and were as low as 0.05" around town. The winds were calm to light all day, got breezy around 7pm, but really nothing to write about.

Mountains and deserts got more precipitation. The highest peak nearby received 5" of rain. Deserts 1.5 - 2.5".

That's probably a good thing. No one needs flash floods and mud slides and that water would be channeled to the ocean anyway.

It's not like we would build new reservoirs to catch flood water. Might threaten the blue-tailed spotted ant.

. Ding Ding Ding Ding! Another good use for that state budget surplus.
