ADVISORIES:

A NEW Blue-Green Algae warning has been issued for Tenmile Lakes in Coos County. A Blue-Green Algae warning has been lifted for Walterville Pond, Dorena Reservoir and Dexter Reservoir,  but continues for Fern Ridge Reservoir and  at Devils Lake. 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 will be moving over us bringing back the chance of showers. A frontal system has pushed through the Pacific Northwest bringing cooler air and enhancing the chance of showers. Another frontal system will approach Oregon late in the week
