HEALTH ADVISORIES
- THE OREGON HEALTH AUTHORITY HAS ISSUED A PUBLIC HEALTH ADVISORY FOR UNSAFE LEVELS OF FECAL BACTERIA IN OCEAN WATERS AT OCEANSIDE BEACH IN TILLAMOOK COUNTY. PEOPLE SHOULD AVOID DIRECT CONTACT WITH THE WATER IN THIS AREA UNTIL THE ADVISORY IS LIFTED. UNSAFE LEVELS OF FECAL BACTERIA CAN CAUSE DIARRHEA, STOMACH CRAMPS, SKIN RASHES, UPPER RESPIRATORY INFECTIONS, AND OTHER ILLNESSES. CHILDREN, ELDERLY, AND THOSE WITH A COMPROMISED IMMUNE SYSTEM SHOULD USE EXTRA CAUTION AS THEY ARE MORE VULNERABLE TO TO ILLNESSES FROM WATERBORNE BACTERIA. VISITORS SHOULD AVOID WADING IN AREA CREEKS, POOLS OF WATER ON THE BEACH, OR IN DISCOLORED WATER, AND STAY CLEAR OF WATER RUNOFF FLOWING INTO THE OCEAN. LEVELS OF FECAL BACTERIA TEND TO BE HIGHER IN THESE TYPES OF WATER SOURCES.
- 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 graphics for days 3-7 Monday through Friday show no major frontal systems moving into Oregon, but a cold front will be to our northwest next Thursday, then pushing into the Pacific Northwest next Friday.
