ADVISORIES:

• A RED FLAG WARNING IS IN EFFECT FROM 1 PM UNTIL 8 PM THURSDAY FOR GUSTY WINDS AND LOW HUMIDITY FOR THE KLAMATH BASIN AND THE FREMONT-WINEMA NATIONAL FOREST. A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS ARE EITHER OCCURRING NOW, OR WILL SHORTLY. A COMBINATION OF STRONG WINDS, LOW RELATIVE HUMIDITY, AND WARM TEMPERATURES CAN CONTRIBUTE TO EXTREME FIRE BEHAVIOR.
• A RED FLAG WARNING IS IN EFFECT UNTIL 8 PM THIS EVENING FOR GUSTY WINDS AND LOW HUMIDITY FOR THE WILLAMETTE VALLEY, THE NORTHERN OREGON CASCADE FOOTHILLS, THE  MT. HOOD NATIONAL FOREST WEST OF CASCADE CREST. THE AFFECTED AREAS ARE LOCATIONS IN THE VICINITY OF THE WESTERN COLUMBIA RIVER GORGE.  A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS ARE EITHER OCCURRING NOW, OR WILL SHORTLY. A COMBINATION OF STRONG WINDS, LOW RELATIVE HUMIDITY, AND WARM TEMPERATURES CAN CONTRIBUTE TO EXTREME FIRE BEHAVIOR.
• A RED FLAG WARNING IS IN EFFECT UNTIL 10 PM TONIGHT FOR GUSTY WINDS AND LOW HUMIDITY FOR THE CENTRAL MOUNTAINS OF OREGON, AND THE LOWER COLUMBIA BASIN OF OREGON. A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS ARE EITHER OCCURRING NOW, OR WILL SHORTLY. A COMBINATION OF STRONG WINDS, LOW RELATIVE HUMIDITY, AND WARM TEMPERATURES CAN CONTRIBUTE TO EXTREME FIRE BEHAVIOR.

HEALTH ADVISORIES:

• THE HEALTH ADVISORY HAS BEEN RE-ISSUED FOR UPPER KLAMATH LAKE. THE LAKE IS LOCATED OFF OREGON ROUTE 140, 15 MILES WEST OF KLAMATH FALLS IN KLAMATH COUNTY. WATER MONITORING HAS CONFIRMED THE LEVEL OF CYNOTOXINS (FROM HARMFUL ALGAE TOXINS) IS ONCE AGAIN ABOVE RECREATIONAL GUIDELINES FOR HUMAN EXPOSURE. PEOPLE AND ESPECIALLY SMALL CHILDREN AND PETS SHOULD AVOID RECREATING IN AREAS WHERE THE WATER IS FOAMY, THICK LIKE PAINT, PEA-GREEN, BLUE-GREEN OR BROWNISH-RED IN COLOR, IF A THICK MAT OF CYANOBACTERIA (HARMFUL ALGAE) IS VISIBLE IN THE WATER, OR BRIGHT GREEN CELLS ARE SUSPENDED IN THE WATER COLUMN. IF YOU OBSERVE THESE SIGNS IN THE WATER ARE ENCOURAGED TO AVOID SWIMMING AND HIGH-SPEED WATER ACTIVITIES SUCH AS WATER SKIING OR POWER BOATING, IN AREAS WHERE BLOOMS ARE IDENTIFIED.
• A RECREATIONAL HEALTH ADVISORY HAS BEEN ISSUED FOR DORENA RESERVOIR, LOCATED 6 MILES EAST OF COTTAGE GROVE IN LANE COUNTY. WATER MONITORING HAS CONFIRMED THE PRESENCE OF HARMFUL ALGAE ABOVE OREGON HEALTH AUTHORITY RECREATIONAL VALUES FOR CELL COUNTS. HARMFUL ALGAE AT THIS LEVEL ARE LIKELY TO BE ASSOCIATED WITH CYANOTOXIN CONCENTRATIONS THAT CAN BE HARMFUL TO HUMANS AND ANIMALS. RECREATIONAL VISITORS ARE ADVISED TO ALWAYS BE ALERT TO SIGNS OF HARMFUL ALGAE AND AVOID AREAS WITH VISIBLE SCUM THAT LOOKS FOAMY, THICK LIKE PAINT, PEA-GREEN, BLUE-GREEN, OR BROWNISH, OR WHERE SMALL BRIGHT-GREEN CLUMPS ARE FLOATING IN THE WATER. PEOPLE SHOULD AVOID SWIMMING AND HIGH-SPEED WATER ACTIVITIES SUCH AS WATER SKIING OR POWER BOATING, IN AREAS WHERE BLOOMS ARE IDENTIFIED.
• A PUBLIC HEALTH ADVISORY HAS RE-ISSUED FOR DETROIT LAKE, LOCATED 46 MILES SE OF SALEM. THE LAKE SPANS BOTH LINN AND MARION COUNTIES.  WATER MONITORING HAS CONFIRMED THE PRESENCE OF HARMFUL ALGAE ABOVE OREGON HEALTH AUTHORITY RECREATIONAL VALUES FOR CELL COUNTS.

• 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.

Here is my weekly weather quiz question for the last time. What is a “Fallstreak?”  Here is the correct answer. A Fallstreak is the same as Virga; streaks or wisps of precipitation falling from a cloud but evaporating before reaching the ground. In certain cases, shafts of virga may precede a microburst.  I’ll have a new weekly weather forecasts for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.

Here is my weekly weather quiz question for the last time. What is a “Fallstreak?”  Here is the correct answer. A Fallstreak is the same as Virga; streaks or wisps of precipitation falling from a cloud but evaporating before reaching the ground. In certain cases, shafts of virga may precede a microburst.  I’ll have a new weekly weather forecasts for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
