FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA
NATIONAL WEATHER SERVICE EUREKA CA
301 PM PDT FRI OCT 9 2026
..BREEZY WESTERLY WINDS AND LOW RH FRIDAY AFTERNOON
..STRONG NORTHWEST WINDS IN EXPOSED ARES SATURDAY AND SUNDAY
DISCUSSION
UNSEASONABLY HOT AND DRY CONDITIONS HAVE FINALLY EASED
TODAY WITH INTERIORS HIGHS CLOSER TO 90 AND RH AROUND 20 PERCENT.
SLIGHTLY STRONGER ONSHORE WIND HAS BUILT WITH GUSTS UP TO 30 MPH
ON HIGH RIDGES. A SWEEPING COLD FRONT WILL GREATLY REDUCE
TEMPERATURES AND INCREASE RH INTO SATURDAY, THOUGH NO RAIN IS
FORECAST. VERY STRONG NORTH WINDS ARE MOST LIKELY THIS WEEKEND AND
WILL ENHANCE FIRE DANGER DESPITE INCREASING RH ALONG EXPOSED
RIDGES AND CLOSE TO SHORE, ESPECIALLY AS WINDS TURN MORE EAST
SATURDAY NIGHT AND INTO SUNDAY.
