331 AM PDT SUN MAR 15 2026
KEY MESSAGES
* BREEZY NORTH IN THE COLORADO RIVER VALLEY TODAY AND TOMORROW
WILL MAKE FOR CHOPPY WAVES ON LAKE MOHAVE AND LAKE HAVASU.
* A SIGNIFICANT WARMING TREND WILL CONTINUE INTO NEXT WEEK WITH
LONG-STRANDING MARCH HEAT RECORDS LIKELY TO BE BROKEN ACROSS
MUCH OF THE WESTERN US BY THE END OF THE WEEK.
DISCUSSION
THROUGH SATURDAY.
UPPER-LEVEL FLOW WILL BECOME MORE NORTHERLY TODAY, FUNNELING WINDS
DOWN THE COLORADO RIVER VALLEY. 15 TO 25 MPH NORTHERLY WINDS WITH
GUTS UP TO 40 MPH ARE EXPECTED DOWN THE COLORADO RIVER VALLEY TODAY
AND TOMORROW. THESE BREEZY WINDS WILL MAKE FOR HAZARDOUS BOATING
CONDITIONS WITH CHOPPY 1 TO 3 FOOT WAVES EXPECTED ON AREA LAKES. A
LAKE WIND ADVISORY WILL GO INTO EFFECT LATER THIS MORNING AS WINDS
BEGIN TO PICK UP AND WILL CONTINUE THROUGH MONDAY EVENING.
NORTH WINDS WILL LINGER DOWN THE COLORADO RIVER VALLEY INTO
TUESDAY, BUT WILL NOT POSE AS MUCH OF A THREAT TO BOATERS AS THEY
WILL NOT BE AS STRONG.
TEMPERATURES TODAY WILL BE SLIGHTLY "COOLER" THAN YESTERDAY, BUT
THEY WILL STILL TOP OUT AROUND 6 TO 12 DEGREES ABOVE NORMAL.
BEGINNING MONDAY, TEMPERATURE WILL BEGIN TO HEAT UP AS A RIDGE OF
HIGH PRESSURE SHIFTS INLAND AND AMPLIFIES OVER THE SOUTHWESTERN US.
AS THIS RIDGE MOVES OVERHEAD AND AMPLIFIES, WE WILL SEE TEMPERATURES
SOAR TO 20+ DEGREES ABOVE NORMAL DURING THE SECOND HALF OF THE WEEK,
THREATENING NUMEROUS DAILY RECORDS AND EVEN SOME MONTHLY RECORDS.
THESE HOTTER THAN NORMAL TEMPERATURES WILL YIELD WIDESPREAD MINOR-TO-
MODERATE HEATRISK (LEVELS 1 AND 2 OF 4) ACROSS SOUTHERN NEVADA,
SOUTHEASTERN CALIFORNIA, AND NORTHWESTERN ARIZONA. AN EXTREME HEAT
WATCH HAS BEEN ISSUED FOR DEATH VALLEY NATIONAL PARK, THE COLORADO
RIVER VALLEY, AND PORTIONS OF SAN BERNARDINO COUNTY FOR WEDNESDAY
THROUGH FRIDAY. A SECOND EXTREME HEAT WATCH WILL GO BE IN EFFECT
THURSDAY AND FRIDAY FOR THE LAS VEGAS VALLEY, SOUTHERN CLARK COUNTY,
AND SOUTHERN MOHAVE COUNTY. THOSE WITHOUT THE CHANCE TO ACCLIMATE TO
THE HEAT (I.E., PEOPLE TRAVELING TO THE DESERT SOUTHWEST FROM OUT OF
TOWN FOR SPRING BREAK), HEAT SENSITIVE INDIVIDUALS, AND PEOPLE
WITHOUT ACCESS TO ADEQUATE COOLING OR HYDRATION WILL BE THE MOST AT
RISK FOR ADVERSE HEAT RELATED IMPACTS AND SHOULD TAKE PROPER
PRECAUTIONS TO MINIMIZE THEIR CHANCES OF BEING NEGATIVELY IMPACTED
BY THE HEAT. SOME EXAMPLES OF PREVENTATIVE MEASURES INCLUDE, BUT ARE
NOT LIMITED TO: WEARING LOOSE, LIGHT COLORED CLOTHING, WEARING
SUNSCREEN, AND TAKING EXTRA CARE TO REMAIN HYDRATED.
