Here is my weekly weather quiz question. What is a“Closed Low?” 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 Pressure Trough (Shaded “U” shape with blue arrows) continues the chance for rain. The graphics for days 1-3 show the front next frontal system headed our way Sunday. We’ll have a break from the rain today. The graphics for days 3-7 show the series of complex frontal systems that are headed our way Tuesday and next Saturday.
Note: Looks like rain gear is what to wear for Saturday’s Civil War Game. It’s going to get chilly too.

ADVISORIES:
- A WIND ADVISORY IS IN EFFECT FROM 2 PM SATURDAY UNTIL 4 AM SUNDAY FOR JACKSON COUNTY, AND THE KLAMATH BASIN,
- A HIGH WIND WARNING IS IN EFFECT FROM P PM SATURDAY THROUGH 4 AM SUNDAY FOR NORTHERN AND EASTERN KLAMATH COUNTY, AND WESTERN, CENTRAL, AND EASTERN LAKE COUNTY.
- A HIGH WIND WATCH IS IN EFFECT FROM LATE SATURDAY NIGHT THROUGH SUNDAY AFTERNOON FOR NORTHERN AND EASTERN KLAMATH COUNTY, AND WESTERN, CENTRAL, AND EASTERN LAKE COUNTY.
- A Health Advisory remains in effect for the Link and Klamath from Keno Dam to J.C. Boyle Dam (downstream from Keno Dam). Water monitoring has confirmed the presence of blue-green algae and the toxins they produce. These toxin concentrations can be harmful to humans and animals. People should always avoid areas with visible scum that looks foamy, scummy, thick like paint, pea-green, blue-green or brownish-red. Swimming and high-speed water activities such as water skiing or power boating where ingestion and inhalation exposure can occur is discouraged. Swallowing or inhaling water droplets as a result of these water activities in areas where a bloom has been identified, or an advisory issued, can expose people to the toxins being produced. Although toxins are not absorbed through the skin, people who have skin sensitivities that come into contact with a bloom may experience a puffy, red rash at the affected area.
- A Health Advisory HAS BEEN LIFTED for Howard Bay (also known locally as Howards Bay or Howard’s Bay), located in the southwest corner of Upper Klamath Lake including Shoalwater Bay to the north and all of Upper Klamath Lake. These areas of Upper Klamath Lake are located off Oregon Route 140, 15 miles west of Klamath Falls in Klamath County. Please remember that blooms can still come and go, so OHA advises pet owners to avoid areas where the water is foamy, scummy, thick like paint, pea-green, blue-green or brownish red in color, or if a thick mat of blue-green algae is visible in the water, or bright green cells are suspended in the water column.
- A Health Advisory remains in effect for Willow Creek Reservoir, located just east of the town of Heppner in Morrow County. Water monitoring has confirmed the presence of blue-green algae and the toxins they produce in the reservoir. These toxin concentrations can be harmful to humans and animals. People should always avoid areas with visible scum that looks foamy, scummy, thick like paint, pea-green, blue green or brownish red. Swimming and high-speed water activities such as water skiing or power boating where ingestion and inhalation exposure can occur is discouraged. Swallowing or inhaling water droplets as a result of these water activities in areas where a bloom has been identified, or an advisory issued, can expose people to the toxins being produced. Although toxins are not absorbed through the skin, people who have skin sensitivities that come into contact with a bloom may experience a puffy, red rash at the affected area. Drinking water directly from Willow Creek Reservoir at this time is especially dangerous. OHA Public Health Division officials advise campers and other recreational visitors that toxins cannot be removed by boiling, filtering or treating water with camping-style filters.
- A Health Advisory remains in effect for Coffenbury Lake, located at Fort Stevens State Park about five miles northwest of US-101 ALT, Northwest Ridgefield Road near Warrenton in Clatsop County. Water monitoring has confirmed the presence of blue-green algae that can produce toxins in Coffenbury Lake. These blue-green algae levels are likely to be associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. People should always avoid areas with visible scum that looks foamy, scummy, thick like paint, pea-green, blue-green or brownish-red. Swimming and high-speed water activities such as water skiing or power boating where ingestion and inhalation exposure can occur are discouraged. Swallowing or inhaling water droplets as a result of these water activities in areas where a bloom has been identified or an advisory issued, can expose people to the toxins that can be produced. Although toxins are not absorbed through the skin, people with skin sensitivities who come into contact with a bloom may experience a puffy, red rash at the affected area. Drinking water directly from Coffenbury Lake at this time is especially dangerous. OHA Public Health Division officials advise campers and other recreational visitors that toxins cannot be removed by boiling, filtering or treating water with camping-style filters.
- A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson 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.
