April 26, 2019 - The National Weather Service Hanford Office reports as the snowpack continues to melt with the warming weekend temperatures, remember that mountain rivers and streams are cold and can be very swift!
People in or near area lakes, rivers, and streams should remain cautious to the dangers of cold springtime waters.
If exposed to cold waters, even experienced swimmers can lose muscle control very quickly, and any fast flowing water will make rescue difficult.
Practice cold water safety techniques or avoid going into the water.
Recognize the signs of hypothermia; such as shivering, cold hands and feet, poor coordination or loss of dexterity, and mental sluggishness.
Alcoholic beverages can speed the onset and progression of hypothermia.
Hydrologic Outlook
HYDROLOGIC OUTLOOK CAZ190>196-261715- HYDROLOGIC OUTLOOK National Weather Service HANFORD CA 1007 AM PDT Thu Apr 25 2019 ...RISING WATER LEVELS ANTICIPATED ON RIVERS AND STREAMS THROUGH THE WEEKEND... The combination of above normal temperatures and rapid snowmelt over the higher elevations of the Sierra will accelerate runoff and generate diurnal water rises on area streams and rivers during the next few days. Many rivers in the foothills and higher elevations of the Sierra could rise to near bankful this weekend. In Yosemite National Park, the California-Nevada River Forecast Center forecasts the Merced River at Pohono Bridge to crest approximately a half foot below its respective Flood stage early Saturday morning and again early Sunday morning. Hikers, recreational boaters and campers should remain alert for rising waters on area streams and rivers during the next few days and be prepared to move to a place of safety if the threat of flooding becomes imminent. Keep in mind that rivers pose dangerous, life threatening hazards at this time of year due to their swift currents and very cold water temperatures. Fifteen minutes or less exposure to the icy cold waters of a river can lead to hypothermia. Strong undercurrents can carry even an experienced swimmer into dangerous parts of the river. Don`t become the next drowning victim or the victim of a water rescue! Stay tuned to NOAA Weather Radio or your favorite media source for further hydrologic updates.
