Advisories: There is a Blue Green Algae warning that continues for Dexter Reservoir. 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, flat now) will strengthen (grow more of a hump) and cover the Pacific Northwest for the next 7 days. That means increasing sunshine and temperatures. About half of the country is going to be very hot for the next few days as we warm up to near the 90 degree mark and then drop back down a bit.
