Advisories:

• A FREEZE WARNING IS IN EFFECT FROM 11 PM THIS EVENING THROUGH 10 AM WEDNESDAY FOR THE SOUTH CENTRAL OREGON COAST AND THE CURRY COUNTY COAST.
• A FREEZE WATCH IS IN EFFECT FROM WEDNESDAY EVENING THROUGH THURSDAY MORNING FOR THE SOUTH CENTRAL OREGON COAST AND THE CURRY COUNTY COAST.

A Blue-Green Algae warning  has been cancelled for Devils Lake while the warning continues for Tenmile Lakes in Coos County, Fern Ridge Reservoir, Lost Creek Lake, and Willow Creek Reservoir (NE Oregon). 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 high pressure ridge (Shaded “Arch” shape) will be drawing much colder air down to the Pacific Northwest. A frontal system pushed through the West and another cold front will push down from the northwest (Blue lines on map) bringing much colder temperatures our way.
