VALID 00Z MON 09 FEB 2026 - 00Z MON 16 FEB 2026
...WINDY WITH POTENTIAL FOR FLOODING RAINFALL THIS WEEKEND ALONG
AND NEAR A NEARLY STATIONARY FRONT INTO THE EARLY PART OF THE
UPCOMING WEEK...
A SLOW MOVING COLD FRONT WILL BE THE FOCUS FOR UNSETTLED WEATHER
THROUGH THE WEEKEND AND INTO THE EARLY PORTION OF THE UPCOMING
WEEK WITH POTENTIAL HAZARDS INCLUDING HEAVY TO EXCESSIVE
RAINFALL, STRENGTHENING WINDS AND A FEW THUNDERSTORMS. THE PASSAGE
OF AN UPPER LEVEL DISTURBANCE TO THE SOUTH OF THE ISLANDS WILL
SUPPORT AN EXPANSION OF THE RAINFALL THREAT BEFORE HIGH PRESSURE
BUILDS TO THE NORTH OF THE ISLAND. ON THE ONE HAND...THE EASTERLY
FLOW WILL BE HELPING TO DRAW DRIER AIR WESTWARD LEADING TO
DECREASING AREAL COVERAGE OF RAIN FALL BY TUESDAY OR
WEDNESDAY...THE PRESSURE GRADIENT BETWEEN THE SURFACE HIGH AND THE
UPPER LEVEL DISTURBANCE WILL PROLONG THE BREEZY TO WINDY
CONDITIONS INTO MID-WEEK, THE ECMWF HAS TENDED TO LEAD THE GFS IN
HANDLING THE MID-LATITUDE SYNOPTIC SYSTEM OVER THE PACIFIC WHICH
WAS HELPING DRIVE AND DEFINE THE SURFACE BOUNDARY.
