• A Blue-Green Algae health advisory is in effect for Howard Bay (sometimes called Howards Bay or Howard’s Bay) in Upper Klamath Lake. It now includes all of Agency and Upper Klamath Lakes. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified.

It now includes the Crooked River Arms. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified.

Here is my weekly weather quiz question for the last time. What is a “Stilling Basin?” Here is the correct answer. A Stilling Basin, in hydrologic terms, is a basin constructed to dissipate the energy of fast-flowing water (e.g., from a spillway or bottom outlet), and to protect the streambed from erosion. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count.

Upper level Low Pressure (Shaded “U” shape with blue arrows) gives us the impetus for the change in our weather pattern. A frontal system moved through the Pacific Northwest keeping us in showers. Take a look at the frontal system that will be moving in Tuesday. High Pressure at the surface (“H” shown offshore) and aloft will take over bringing back the sunshine and warmer temperatures. The 2016 Olympic Team Trials that continue through Sunday at Hayward Field will encounter the chance of showers through the rest of the competition, as you can see in the forecast.

The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

A weakening area of High Pressure (Shaded “Arch” shape with blue arrows) keept us dry and in sunshine again today.  Upper level Low Pressure (Shaded “U” shape with blue arrows) gives us the impetus for a change in our weather pattern. A frontal system is shown approaching the coast on Friday. There’s another cause for increased rain chances. Take a look at the frontal system that will be moving through the Pacific Northwest a week from today. The 2016 Olympic Team Trials that run through next Sunday July 10th at Hayward Field will encounter at least a chance of showers, as you can see in the forecast, from Thursday through the rest of the trials.
