No winner this week. Here is my weekly weather quiz question for the last time. What or where is “Pangea?” Here is the correct answer. This definition is from Britanica.com:

 

________________

 

Advisories: 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. 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 a mix of clouds and sun in the 80s with a slight chance of a shower or thunderstorm.

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 so you can see the sky.

The Grass Pollen Count is listed as Low at 2 and Tree pollen is Low at 2 as of 8/9/13 according to Oregon Allergy Associates.
