Note: Weather is a constantly changing phenomenon and weather forecasting is a combination of science, experience, and intuition. The accuracy of any given forecast can chance due to unexpected changes in atmospheric conditions, so there are no guarantees the the actual weather will conform to the projected forecast.

ADVISORIES

  • A RED FLAG WARNING IS IN EFFECT FROM 11 AM UNTIL 8 PM MONDAY FOR LOW RELATIVE HUMIDITY AND WINDY CONDITIONS FOR THE LOWER COLUMBIA BASIN OF OREGON.
  • A HEAT ADVISORY IS IN EFFECT UNTIL 8 PM THIS EVENING FOR THE LOWER COLUMBIA BASIN OF OREGON.

HEALTH ADVISORIES

  • A RECREATIONAL USE HEALTH ADVISORY IS IN EFFECT FOR GALESVILLE RESERVOIR IN DOUGLAS COUNTY DUE TO THE PRESENCE OF A CYANOBACTERIA BLOOM. PEOPLE SHOULD AVOID SWIMMING AND HIGH SPEED WATER ACTIVITIES, SUCH AS WATER SKIING OR POWER BOATING, IN AREAS OF THE RESERVOIR WHERE BLOOMS ARE, AS THE MAJOR ROUTE OF EXPOSURE IS INGESTION OF WATER. TOXINS ARE NOT ABSORBED THROUGH THE SKIN, HOWEVER, THOSE WITH SKIN SENSITIVITIES MAY GET A PUFFY RED RASH. THE OREGON HEALTH AUTHORITY ENCOURAGES PEOPLE TO VISIT THE GALESVILLE RESERVOIR AND ENJOY ACTIVITIES SUCH AS FISHING, CAMPING, HIKING, BILKING, PICNICKING, BIRD WATCHING, CANOEING, AND KAYAKING. BOATING IS SAFE AS LONG AS SPEEDS DO NOT CREATE EXCESSIVE WATER SPRAY.. SPRAYS COULD LEAD TO THE RISK OF INHALING CYANOTOXINS.
