Axiom-4 will be returning to Earth, with splashdown ~2:31AM. It will be approaching on a similar reentry path to the CRS-32 mission that generated a sonic boom on 5/24.
We are looking at low clouds and fog around the area at the time, so view of the reentry plasma trail might limited.

Even very small quakes can be felt if you are nearby (and a shallow quake is closer to people on the surface). But there is not much to be said about an M2.7 except that it happened

It took some time, but we managed to get to clearing across most (but not all) Inland areas. Ventura County is still hanging onto the clouds right now.
Deeper marine layer today meant the clouds/fog pushed farther inland. Here's a clearing comparison between yesterday and today. @nbcla.com

Felt that quake in the NoHo area. Got the alert and took cover, took some time for the shaking to arrive.

California Snowpack Update ❄️
Apr 1 is considered to be the "peak" of the state's snowpack, which acts as a water bank account through the next several months. As snow melts, the runoff is captured by a network of reservoirs.
This year we are at 96% of average, still considered a healthy snowpack.

What a difference 1 day makes...
We are much cooler across the region today compared to yesterday at this time. Cooling continues into the weekend, along with drizzle and light rain chances.
Next week looks cool as well. @nbcla.com #LosAngeles #CAwx #SouthernCalifornia

Santa Ana Winds helped to push coastal temperatures up today...while inland areas stayed level or cooled a few degrees compared to yesterday.
Everyone will get much cooler tomorrow as the pattern starts to shift back to more of what we would see during winter.

The next round of heavier rainfall is about to move into LA County. This is the cold front sweeping across the region from west to east.
This will likely bring the heaviest rainfall of the day, and our concern for possible flooding problems as well as mudslides/debris flows near the burn scars.

The #PalisadesFire is moving rapidly with the strong winds. There is possibility for long range spotting.
If you feel unsafe, leave! Do not wait to be told to evacuate.
Do not try to defend your property with a garden hose, it won’t do anything in a situation like this. @nbcla.bsky.social
