The region is bracing for a prolonged period of intense heat and high humidity as monsoon moisture continues to flow in from the east. This weather pattern is expected to persist into early August, bringing with it a range of weather alerts and hazards.
Residents and visitors alike are advised to take precautions to stay safe in the heat, as temperatures soar and humidity levels rise. From heat advisories to beach hazards, understanding the forecast is crucial for navigating the week ahead.
Heat Warnings and Advisories
A heat advisory is in effect for the coast from 10am Thursday until 8pm Monday. Highs along the beaches are expected to range from the mid-70s to mid-80s, while areas just 5 to 10 miles inland will see temperatures closer to 90 degrees.
Inland areas are also under a Heat Advisory until 8pm Monday, with highs soaring between 90 and 100 degrees. The mountains and deserts are facing an Extreme Heat Warning with temperatures in the mountains expected to reach the 90s and some lower elevations, like Campo, warming up to 105 degrees. The deserts will experience extreme temperatures between 113 and 119 degrees, with the peak heat expected on Saturday.
The nights will also be unusually warm, with daily highs and morning lows trending 5 to 10 degrees above normal for most of the county. Coastal areas, inland regions, and the mountains will spend most nights in the 70s, while the deserts will remain in the 100s and 90s, only dropping into the 80s by sunrise.
Monsoon Showers and Thunderstorms
There is a slight chance of monsoon showers and thunderstorms over the mountains on Thursday and Friday, with the possibility of more storms on Sunday and Monday. These storms could bring heavy raingusty windsflooding and even small hail.
As Tropical Cyclone Elida passes hundreds of miles to the west, it will pump in higher humidity, exacerbating the monsoon flow from the east. This combination is expected to bring even higher humidity and a greater chance of showers and thunderstorms, even along the coast and in the valleys. Several more tropical storms are anticipated to form south of Baja, Mexico, into early August, potentially impacting the region’s weather.
Beach Hazards and Safety Tips
Those looking to beat the heat at the beaches should be prepared for another round of elevated surf. A Beach Hazards Statement is in effect from 5am Thursday until 8pm Sunday, with waves of 5 to 7 feet and strong rip currents. High tides peaking at 5.5 to 6.5 feet, combined with elevated surf, will lead to minor coastal flooding during high tides.
To stay safe in the heat, it is essential to take precautions. Ensure that outdoor pets have safe shelter and cool water. Never leave children or pets in the car, as temperatures inside can rise rapidly. Wear light-weight, light-colored, loose-fitting clothing and stay hydrated. Avoid strenuous outdoor activities and enjoy air conditioning whenever possible. If working in the heat, take frequent breaks and drink plenty of water.
Additionally, check your cars for loose tire tread or parts that could spark a fire. Have a go bag and working flashlights ready in case of an emergency or power outage. Prune and trim trees and shrubs to create a defensible space around your home.
