...WARMER TEMPERATURES TO BRING INCREASED SNOWMELT...
A STRONG HIGH PRESSURE AREA WILL BUILD OVER CENTRAL CALIFORNIA THIS WEEKEND. THIS WILL
BRING MUCH WARMER TEMPERATURES TO THE
REGION...ALONG WITH INCREASED SNOWMELT IN THE SOUTHERN SIERRA NEVADA.
THE INCREASED RUNOFF WILL BRING RISES ON MANY MOUNTAIN STREAMS AND RIVERS. THESE
WATERS WILL BE QUITE COLD AND SWIFT MOVING...AND
WHILE THEY MAY APPEAR INVITING...CAN BE QUITE DANGEROUS.
IF YOU ARE PLANNING OUTDOOR ACTIVITIES IN THE MOUNTAINS THIS WEEKEND OR EARLY NEXT
WEEK...BE CAREFUL IN AND NEAR AREA RIVERS AND LAKES...AND USE COMMON SENSE. ANYONE
CAUGHT IN THE COLD WATER CAN QUICKLY EXPERIENCE HYPOTHERMIA...WHICH IS A RAPID LOSS OF
BODY
HEAT AND CAN BE FATAL.
IF CAMPING NEAR STREAMS...REMEMBER THAT THE HIGHEST STREAM FLOWS OCCUR AT NIGHT...
USUALLY BETWEEN THE HOURS OF 10 PM AND 3 AM...NOT
DURING THE WARMEST PART OF THE DAY. KEEP YOUR GEAR FAR ENOUGH AWAY FROM WATER TO
AVOID ANY SUDDEN OR UNEXPECTED RISES IN WATER
LEVELS.
