An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) returns hot weather and the winds have returned the haze and smoke from Oregon wildfires. It seems the hazy smoke filled air kept today’s high temperature in Eugene well bellow what was expected. The graphics for days 3-7  show a frontal system moving through Oregon Thursday, then another front pushing through the Pacific Northwest next Sunday.

Here is my weekly weather quiz question for the last time. What is  “Frazil Ice?” Here is the correct answer.  Frazil Ice: In hydrologic terms, fine spicules, plates, or discoids of ice suspended in water. In rivers and lakes, frazil is formed in supercooled, turbulent water. I’ll have a new weekly weather quiz question for you on 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.

Did Drought Wipe Out A Civilization?

Here is my weekly weather quiz question for the last time. What is  “Frazil Ice?” Here is the correct answer.  Frazil Ice: In hydrologic terms, fine spicules, plates, or discoids of ice suspended in water. In rivers and lakes, frazil is formed in supercooled, turbulent water. I’ll have a new weekly weather quiz question for you on 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 Low (Shaded “U” shape formed by arrows) returns the warmer air ahead of it and also brings the chance of mainly mountain thunderstorms with the increased marine airflow. The graphics for days 3-7  show a frontal system trying to move into Oregon Thursday.

Note: The haze may have been gone at the Eugene Airport but it was still present a tree level in the South Hills.

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 UPDATED TO INCLUDE ONLY THE WILLAMETTE RIVER’S ROSS ISLAND LAGOONCATED 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. ALTHOUGH TOXINS ARE NOT ABSORBED THROUGH THE SKIN, PEOPLE WHO HAVE SKIN  SENSITIVITIES MAY EXPERIENCE A PUFFY RED RASH AT THE AFFECTED AREA. DRINKING WATER DIRECTLY  IS ESPECIALLY DANGEROUS TOXINS CANNOT BE REMOVED BY ANY TECHNIQUE.
  • A RECREATIONAL USE HEALTH ADVISORY HAS BEEN ISSUED FOR WILLOW CREEK RESERVOIR, LOCATED JUST EAST OF THE TOWN OF HEPNER IN MORROW COUNTY.   WATER MONITORING HAS CONFIRMED THE CYANOBACTERIA AND THE TOXINS THEY PRODUCE ARE ABOVE RECREATIONAL VALUES FOR HUMAN EXPOSURE. THE CYNOTOXIN CONCENTRATIONS FOUND CAN BE HARMFUL TO HUMANS AND ANIMALS. PEOPLE SHOULD AVOID SWIMMING AND HIGH-SPEED WATER ACTIVITIES LIKE WATER SKIING OR POWER BOATING IN AREAS OF THE LAKE WHERE CYNOTOXINS ARE IDENTIFIED. ALTHOUGH TOXINS ARE NOT ABSORBED THROUGH THE SKIN, PEOPLE WHO HAVE SKIN  SENSITIVITIES MAY EXPERIENCE A PUFFY RED RASH AT THE AFFECTED AREA.

An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) has weakened  and that kept the temperatures up. An upper level low (“U” shape formed by arrows) brings in cooler air, but high pressure quickly returns to warm us back up a bit. The graphics for days 3-7  show no frontal systems trying to move into Oregon until next Thursday.

An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) has weakened  and that keept the temperatures up. An upper level low (“U” shape formed by arrows) brings in cooler air, but high pressure quickly returns to warm us back up a bit. The graphics for days 3-7  show no frontal systems trying to move into Oregon, but only surface thermal low pressure sliding through Saturday through Wednesday.
