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) is moving slowly to the North away from us. High pressure will spread our way from the southeast to clear us out. Another low is starting its journey toward the Oregon coast later this week.
The Perseid meteor shower is in progress. The maximum number of “shooting stars” from the comet Swift-Tuttle will be visible after midnight tonight and early Wednesday morning. 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 clear off, at least a bit, so you can see the sky. The meteor shower will continue for the next few days, but the number you might see will slowly taper off.
