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.

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.
  • A PERMANENT HEALTH ADVISORY REMAINS IN EFFECT FOR THE SOUTH UMPQUA RIVER BAR. POOLS IN THE BEDROCK ALONG THE RIVERS EDGE ARE KNOWN TO DEVELOP BLUE-GREEN ALGAE (CYANOBACTERIAL) BLOOMS THAT CAN BE HARMFUL TO PETS AND PEOPLE IF ACCIDENTAL INGESTION OCCURS. SIGNS HAVE BEEN POSTED ALONG SEVERAL ACCESS AREAS ALONG THE  RIVER.

THE WEATHER PATTERN

  • An Upper Level Low Pressure Trough (“U” shape) keeps our weather pattern stable with normal temperatures. The graphics for days 1-3  show a cold front pushing through the Pacific Northwest Sunday. The graphics for days 3-7   Tuesday through Saturday show no frontal activity pushing into or through Oregon during the period until a front shows up to our northwest Wednesday through next Friday. So far the smoke has been staying in Eastern Lane County, but if the winds shift that might not be the case.
