Catalina has low clouds sitting along the western edge of the island, unable to get east of the island thanks to the dry air from the offshore flow.

The view of Two Harbors (one of the lowest points on the island) shows the transition from clouds on the west, to clear sky on the east. @nbcla.com

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 National Hurricane Center’s track forecasts for the 2024 season featured record accuracy, and intensity forecasts were at near-record accuracy, per a report released this week. The NHC is part of the National Weather Service, which is part of NOAA.

FLASH FLOOD WARNING - FRANKLIN AND PALISADES FIRE BURN SCARS UNTIL 8PM.

Life threatening debris flows are imminent or occurring.

There's a chance we might hear a rumble or two of thunder, and pea sized hail is not out of the question.

After the front moves through, this system is mostly done. We will get a few lingering showers overnight into early Friday morning, but not expecting things to be intense.

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.

Current conditions near the #PalisadesFire, gusts are pushing the fire along fast, leading to long range spotting.

Stay out of the area and listen to all official evacuation orders. Have your go bag ready!

If you see fire approaching or don't feel safe, LEAVE!

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

Please stay weather aware over the next few days, regardless of where you live. Keep your phones charged, and be prepared for power outages. @nbcla.bsky.social

This looks similar to the 2011 Pasadena Windstorm, which downed over 1,000 trees and caused numerous power outages. @nbcla.bsky.social

The wind story is a challenge because of the addition of another forecast element: mountain waves. There is support in the atmosphere to cause damaging wind gusts, in excess of 80mph, in communities near the Mountains and Foothills. This would be overnight Tue into Wed. @nbcla.bsky.social

High Wind Warnings are also posted due to the potential of wind gusts of 60-80+ mph, especially in areas near Mountains and Foothills (all of the Valleys, including some typically wind sheltered areas)

Downed trees and power outages are likely. @nbcla.bsky.social

Red Flag Warning has been issued for nearly the entire region (including all of LA County) due to the extreme fire danger presented by the strong winds and very dry fuels.

Any new fires have the potential to grow rapidly, burn intensely, and be very difficult to control. @nbcla.bsky.social
