The remnants of Frances is expected to affect the area Thursday with upwards to 4″ of rain. Those backcountry camping/hiking on Friday (this includes me) should be aware of possible issues crossing streams and low-lying areas. Have a backup plan in place. We may have to change our route or car camp

OUTLOOK…SIGNIFICANT RAINFALL IS POSSIBLE THIS WEEK…STARTING TUESDAY NIGHTAND
CONTINUING INTO FRIDAY.A COLD FRONT WILL PUSH SLOWLY TOWARD THE REGION WHILE THE
REMNANTS OFHURRICANE FRANCES MOVE NORTH ALONG THE FRONTAL BOUNDARY.THE
COMBINATION OF TROPICAL MOISTURE AND THE SLOW MOVING SYSTEM WILLBRING AN EXTENDED
PERIOD OF RAINFALL WITH THE POTENTIAL FOR HEAVYRAIN AT TIMES. THE BEST CHANCE FOR
HEAVY RAIN AT THIS TIME IS DURINGTHE DAY THURSDAY.IT IS STILL TOO EARLY TO
PREDICT RAINFALL AMOUNTS. HOWEVER RAINFALLAMOUNTS OF 2 TO 3 INCHES WITH LOCAL
AMOUNTS OVER 4 INCHES AREPOSSIBLE WITH THIS EVENT. THIS AMOUNT OF RAIN COULD
LEAD TO FLOODING…ESPECIALLY IF IT FALLS OVER A SHORT PERIOD OF TIME.FORTUNATELY
IT HAS BEEN DRY OVER THE PAST TWO WEEKS. PORTLAND HASHAD ONLY ABOUT A THIRD
OF AN INCH OF RAIN OVER THE LAST 16 DAYS.THIS MEANS IT WOULD TAKE MORE
RAINFALL TO CREATE A SATURATEDENVIRONMENT AND TO RAISE STREAM AND RIVER LEVELS TO THE
POINT OFCREATING A FLOOD SITUATION.CONTINUE TO LISTEN TO NOAA WEATHER
RADIO…OR YOUR LOCAL NEWSSTATION…OVER THE NEXT FEW DAYS TO MONITOR THIS SITUATION
FOR THEPOSSIBILITY THAT THE NATIONAL WEATHER SERVICE MAY ISSUE FLOOD
WATCHESFOR ALL OR PART OF THE AREA IF THE POTENTIAL FOR FLOODING BECOMESMORE
LIKELY.$$SJC
