Here is my weekly weather quiz question for the last time. What is  a “Back Door Cold Front?”  Here is the correct answer. A Back Door Cold Front is a cold front moving south or southwest along the Atlantic seaboard and Great Lakes; these are especially common during the spring months. They also occur here in the west as a cold front pushes southward from Canada and then moves from northeast to southwest across the Pacific Northwest usually bringing much colder air down from Canada. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

Advisories:

• A Health Advisory has been issued  for the water around Eagle Ridge County Park on Upper Klamath Lake. The park is located off Highway 140, 15 miles west of Klamath Falls in Klamath County. Water monitoring has confirmed the presence of blue-green algae and the toxins they produce in this area of Upper Klamath Lake. These toxin concentrations can be harmful to humans and animals.
• A Health Advisory has been issued for Detroit Lake, located 46 miles SE of Salem in Marion County. Water monitoring has confirmed the presence of blue-green algae and the toxins they produce in Detroit Lake. These toxin concentrations can be harmful to humans and animals. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.

Advisories:

• A Health Advisory has been issued  for the water around Eagle Ridge County Park on Upper Klamath Lake. The park is located off Highway 140, 15 miles west of Klamath Falls in Klamath County. Water monitoring has confirmed the presence of blue-green algae and the toxins they produce in this area of Upper Klamath Lake. These toxin concentrations can be harmful to humans and animals.
• A Health Advisory has been issued for Detroit Lake, located 46 miles SE of Salem in Marion County. Water monitoring has confirmed the presence of blue-green algae and the toxins they produce in Detroit Lake. These toxin concentrations can be harmful to humans and animals. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.

Advisories:

• A Health Advisory has been issued for Detroit Lake, located 46 miles SE of Salem in Marion County. Water monitoring has confirmed the presence of blue-green algae and the toxins they produce in Detroit Lake. These toxin concentrations can be harmful to humans and animals. People should avoid swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.
• A Permanent Health Advisory remains in effect for the South Umpqua River and Lawson Bar. Pools in the bedrock along the rivers edge are known to develop Blue-green Algae (cyanobacterial) blooms that can be harmful to pets and people if accidental ingestion occurs. Signs have been posted along several access areas along the river.
