There is a Blue-Green Algae warning that continues for Dexter Reservoir and Dorena Reservoir has just been added to the list. Water monitoring has confirmed the presence of blue-green algae that can produce toxins, state public health officials said. The algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided according to the authorities.

An upper level low (“U” shape with blue arrows) has moved to the south and is going to move slowly to the North and East later in the week. The airflow continues to bring a chance of thunderstorms over the mountains and spread smoke from existing wildfires. The weather for the Scandinavian Festival in Junction City that continues through Sunday will be mostly cloudy in the 80s with a slight chance of a thunderstorm. I’ll keep you updated on that as we get closer to the weekend.
The Perseid meteor shower is in progress. The maximum number of “shooting stars” from the comet Swift-Tuttle will be visible after midnight Sunday through Tuesday. There could be as many as 50 sighted per hour as they move from the NE quadrant of the sky. For best viewing go to where there are no city lights to brighten the sky. You also need for the clouds to go away, fat chance of that happening.
