FIRE WEATHER PLANNING FORECAST FOR HAWAII
NATIONAL WEATHER SERVICE HONOLULU HI
417 AM HST FRI MAR 20 2026
DISCUSSION
IN THE BIG PICTURE, TWO SURFACE LOW PRESSURE SYSTEMS WILL MOVE
SLOWLY NORTHEASTWARD THROUGH THE NORTHERN HAWAII REGION INTO THE
WEEKEND, PRODUCING ADDITIONAL PERIODS OF MODERATE TO HEAVY RAIN,
THUNDERSTORMS, AND ELEVATED THREATS FOR FLASH FLOODING. A
COMBINATION OF LOW LEVEL FORCING AND PASSING UPPER LEVEL TROUGHS
WILL DRIVE THESE SMALLER SCALE HEAVY RAIN BAND AND THUNDERSTORM
FORMATIONS. ADDITIONAL WEATHER THREATS INCLUDE STRENGTHENING
SOUTH TO SOUTHWEST KONA WINDS ON SATURDAY THAT WILL PRODUCE DOWN
SLOPING WIND GUSTS IN THE 30 TO 45 MPH RANGE ALONG STEEP NORTH AND
EAST SLOPES OF ISLAND MOUNTAIN RANGES LASTING THROUGH SATURDAY
NIGHT. IMPROVING WEATHER TRENDS WILL DEVELOP FROM WEST TO EAST ON
MONDAY AS WE TRANSITION TO A WET TRADE WIND WEATHER PATTERN
LASTING THROUGH THE END OF NEXT WEEK. TEMPERATURE INVERSION HEIGHTS
NEAR MAUI AND THE BIG ISLAND WILL REMAIN ABOVE 8,000 FEET TODAY.
