Californians, brace yourselvesโthis weekโs weather is throwing one curveball after another! After dealing with atmospheric rivers, flash floods, and even rare snowfall, the state is now facing thick morning fog, a sudden heatwave, and dangerous coastal conditions.
Dense Fog Advisory: Morning Commutes Could Be a Nightmare
The National Weather Service has issued a Dense Fog Advisory for multiple areas across California, particularly in the Central Valley and coastal regions. The advisory will last through Tuesday morning, and visibility may drop to less than a quarter-mile, making highways like I-5, I-80, and Highway 101 especially dangerous for early morning drivers.
If youโre commuting, take extra precautions:
- Use low-beam headlights so you can see without glare.
- Drive slowly and allow more space between you and other vehicles.
- Give yourself extra travel timeโdelays are likely!
Foggy conditions should clear up by mid-morning, but expect some lingering haze in low-lying areas.

From Chilly Mornings to a Sudden Heatwave!
After dealing with chilly winter mornings, Californians are about to get a major temperature shock. A strong high-pressure system is bringing in warm air from the southwest, causing temperatures to rise 10 to 15 degrees above normal.
- San Francisco will reach a comfortable 68ยฐF, but inland areas will climb into the 70s.
- Los Angeles is set to skyrocket into the upper 80sโpossibly hitting 90ยฐF by Wednesday!
- Southern California desert areas will see even hotter conditions, with some locations nearing 95ยฐF!
This rapid heat surge will be a stark contrast to the recent cold spell, so be sure to stay hydrated and dress accordingly!
Coastal Hazards: Sneaker Waves & Rip Currents
If youโre planning a beach day this week, be extra cautious! The National Weather Service has issued a Beach Hazards Statement for much of Californiaโs coastline, warning of sneaker waves and powerful rip currents.
Waves as high as 15 to 18 feet are expected along west-facing beaches, especially in Northern and Central California.
- Avoid standing too close to the shoreโsneaker waves can sweep you away in seconds.
- If caught in a rip current, donโt panic! Swim parallel to the shore until you escape the current.
- Surfers and swimmers should be extremely cautiousโconditions could be deadly.
Whatโs Next? Will Winter Make a Comeback?
While this warm spell will last through midweek, donโt get too comfortable! A low-pressure system is expected to move in by Friday, bringing cooler temperatures and increased cloud cover. Some areas may even see light rain heading into the weekend. For now, expect foggy mornings, summer-like afternoons, and hazardous beach conditions. Stay safe, stay informed, and keep an eye on the ever-changing California skies!
