Advisories: There is a 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 low (Shaded “U” or “O” shape off the coast of northern California) will push northeastward allowing for some cooling and a frontal system will slide down from the northwest. Look for a shower and possibly a thunderstorm this afternoon and evening as the California low sends wavs of moisture to us.
