Here is my weekly weather quiz question for the last time. What is a “Fogbow?” Here is the correct answer. A Fogbow is a rainbow that has a white band that appears in fog, and is fringed with red on the outside and blue on the inside. I’ll have a new weekly weather quiz question 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.

An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) is leaving us as an Upper Level Low (Shaded “U” shape formed by arrows) moves west to east well north of us to keep a cooler air mass over us for a while. Expected it to start seriously cooling down Friday, but ended up only by a few degrees. Today is definitely cooler. The graphics for days 1-3 show a frontal system that moved through cleaning out the haze and smoke, for a while anyway. The graphics for days 3-7  show no frontal systems trying to move into Oregon, but only surface low pressure sliding through.

HEALTH ADVISORIES:

• A PUBLIC HEALTH ADVISORY IS IN EFFECT FOR HIGHER-THAN-NORMAL LEVELS OF BACTERIA IN OCEAN WATERS AT SEAL ROCK STATE PARK BEACH, LOCATED IN LINCOLN COUNTY. WATER SAMPLES INDICATE HIGHER-THAN-NORMAL LEVELS OF FECAL BACTERIA, WHICH CAN CAUSE DIARRHEA, STOMACH CRAMPS, SKIN RASHES, UPPER RESPIRATORY INFECTIONS AND OTHER ILLNESSES. PEOPLE SHOULD AVOID DIRECT CONTACT WITH THE WATER IN THIS AREA UNTIL THE ADVISORY IS LIFTED. THIS APPLIES ESPECIALLY TO CHILDREN AND THE ELDERLY, WHO MAY BE MORE VULNERABLE TO WATERBORN BACTERIA. WHILE THIS ADVISORY IS IN EFFECT AT SEAL ROCK STATE PARK BEACH, VISITORS SHOULD AVOID WADING IN NEARBY CREEKS, POOLS OF WATER ON THE BEACH, OR IN  DISCOLORED WATER, AND STAY CLEAR OF WATER RUNNOFF FLOWING INTO THE OCEAN. EVEN IF THERE IS NO ADVISORY IN EFFECT, OFFICIALS RECOMMEND AVOIDING SWIMMING IN THE OCEAN WITHIN 48 HOURS AFTER A RAINSTORM. OTHER BEACH ACTIVITIES ARE SAFE TO ENJOY.
• A RECREATIONAL USE HEALTH ADVISORY HAS BEEN REISSUED FOR THE WILLAMETTE RIVER’S ROSS ISLAND LAGOON AND EXTENDED TO CATHEDRAL PARK LOCATED ABOUT 1 MILE SOUTH OF DOWNTOWN PORTLAND IN MULTNOMAH COUNTY. THE ADVISORY HAS BEEN ISSUED DUE TO VISUAL CONFIRMATION OF A CYANOBACTERIA BLOOM (HARMFUL ALGAE) IN THE LAGOON. WATER SAMPLES HAVE BEEN TAKEN TO CONFIRM THE TYPE OF CYANOBACTERIA AND THE LEVEL OF POTENTIAL TOXINS THAT MAY BE PRODUCED. DRINKING WATER DIRECTLY FROM THE RIVER WHERE A BLOOM IS IDENTIFIED IS ESPECIALLY DANGEROUS SINCE ANY TOXINS PRODUCED CANNOT BE REMOVED BY ANY BOILING, FILTERING OR TREATING THE WATER WITH CAMPING STYLE FILTERS. NO PUBLIC DRINKING OR POTABLE WATER SYSTEMS ARE AFFECTED. PEOPLE SHOULD AVOID SWIMMING AND HIGH-SPEED WATER ACTIVITIES LIKE WATER SKIING OR POWER BOATING IN AREAS OF  WHERE CYNOTOXINS ARE IDENTIFIED.

An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) has formed over is while the Upper Level Low remains well out over the ocean. This spells H-O-T weather for a few days, but not quite as hot as we first thought. The smoke in the air is responsible for filtering just enough solar radiation to keep us just a little cooler that originally forecast.  The graphics for days 1-3 show High Pressure at the surface over us. The graphics for days 3-7  show frontal activity picks up Friday with a cold front moving through the Pacific Northwest bringing us cooler temperatures.
