..WESTERN WASHINGTON STATE
A ROUND OF HEAVY PRECIPITATION ON TUESDAY LOOKS LIKELY WITH A
STRONG FRONTAL SYSTEM INTO THE REGION MORE IN THE FIRST HALF OF THE
PERIOD (12Z TUES TO 00Z WED). LIMITED INSTABILITY SHOULD KEEP RAIN
RATES IN CHECK, AND LOWER SNOW LEVELS MAY ALLOW FOR MORE
PRECIPITATION TO FALL AS SNOW. SO, WHILE THIS AREA WILL CONTINUE TO
BE MONITORED, NO MARGINAL RISK ERO IS NEEDED STILL AT THIS TIME.
..NORTHEAST FLORIDA
A NEARLY STATIONARY FRONT NEAR THE COAST OF ST. AUGUSTINE/DAYTONA
BEACH MAY SUPPORT SLOW MOVING CONVECTION FORMING OVER/NEAR I-95 IN
THAT AREA. ANY STORMS THAT FORM WILL BE CAPABLE OF PRODUCING HEAVY
RAIN BUT VERY DRY SOILS AND GENERALLY FLAT, FLOOD- AVERSE DRAINAGE
BASINS SHOULD LIMIT THE OVERALL RISK. STILL, ANY STATIONARY STORMS
THAT DO FORM OVER THIS SEMI- URBAN AREA FOR AN EXTENDED PERIOD
COULD RESULT IN LOCALIZED FLOODING/PONDING, SO WILL NEED TO
MONITOR FOR A POSSIBLE MARGINAL RISK UPGRADE.

DAY 3
VALID 12Z WED MAR 25 2026 - 12Z THU MAR 26 2026
