Miserable humidity persists in Southern California

Key Points:

• Tropical Storm Marie, located hundreds of miles southwest of Los Angeles County, is bringing increased humidity, dangerous rip currents, and extreme heat to the region through the week, with temperatures peaking in the 90s and low 100s in some inland areas.
• High surf and coastal flooding are expected on south-facing beaches through Tuesday, making ocean swimming unsafe due to strong rip currents and potential bacteria contamination from recent rains.
• Heat advisories have been issued for Los Angeles County beaches, coastal valleys, and the Santa Monica Mountains for Wednesday and Thursday, expanding to additional counties including Ventura, Santa Barbara, and San Luis Obispo.
• The combination of tropical moisture from Marie and a building ridge of high pressure will cause exceptional humidity levels, with "feels like" temperatures potentially reaching 110 degrees, creating significant heat stress and discomfort.
• Residents are advised to stay hydrated, avoid ocean swimming, monitor weather updates, and use cooling centers if necessary, especially those working outdoors or without air conditioning.
