HEALTH ADVISORIES:

• A PUBLIC HEALTH ADVISORY IS IN EFFECT FOR HIGHER-THAN-NORMAL LEVELS OF BACTERIA IN OCEAN WATERS AT TWIN ROCKS BEACH, LOCATED IN TILLAMOOK 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 TWIN ROCKS 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.

THE CYANOTOXIN CONCENTRATIONS FOUND CAN BE HARMFUL TO TO HUMANS AND ANIMALS. PEOPLE SHOULD AVOID SWIMMING AND HIGH-SPEED WATER ACTIVITIES LIKE WATER SKIING OR POWER BOATING IN AREAS OF THE RESERVOIR 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 FROM THE LAKE IS ESPECIALLY DANGEROUS TOXINS CANNOT BE REMOVED BY ANY TECHNIQUE. DRINKING WATER DIRECTLY FROM THE RESERVOIR AT THIS TIME IS ESPECIALLY DANGEROUS.

Here is my weekly weather quiz question for the last time. What is “Glaciation?”  Here is the correct answer.  Glaciation is the transformation of cloud particles from water drops to ice crystals. Thus, a cumulonimbus cloud is said to have a “glaciated” upper portion. 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.

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 TWIN ROCKS 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.

Here is my weekly weather quiz question for the last time. What is “Glaciation?”  Here is the correct answer.  Glaciation is the transformation of cloud particles from water drops to ice crystals. Thus, a cumulonimbus cloud is said to have a “glaciated” upper portion. 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.
