Here is my weekly weather quiz question for the last time. What is “Acid Precipitation?” Here is the correct answer. Acid Precipitation is precipitation, such as rain, snow or sleet, containing relatively high concentrations of acid-forming chemicals that have been released into the atmosphere and combined with water vapor; harmful to the environment. 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. Good luck.

That cold moved much slower than expected so we had sunshine from Eugene South for most of Sunday. An upper level trough of low pressure (Shaded “U” shape with blue arrows) moves to the east to allow clearing again because a ridge of high pressure (Shaded “Arch” shape with blue arrows). That means well warm up a bit also. Check out days 3-7 show a frontal system moving toward us Wednesday followed by other fronts.

Advisories:

• A Blue-green Algae Health Advisory has been issued for Howard Bay located in Upper Klamath Lake. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily. Cell counts in other parts of the lake were low.
• A  Permanent Health Advisory is 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.
• A Blue-Green Algae Health Advisory remains in effect for Agency Lake. Agency Lake is located just north of Upper Klamath Lake near Klamath Falls along Highway 97 in Klamath County. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily.
