Here is my new weekly weather quiz question. What is an“Acre-foot?” Please remember to post your answer at the bottom of this page. An email will not suffice. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

The Upper level airflow will keep the moisture pouring into the Pacific Northwest. The days 1-3 graphic shows a stationary front that slowly gets pushed southward toward us.. The graphic for days 3-7 shows that frontal system, commonly called a “backdoor” front because it moves in from the opposite direction from which fronts usually come toward us, through the Pacific Northwest to bring in colder air late this coming week. We’re still seeing snow accumulations increasing in the mountains. For mountain snow conditions at the local ski areas check out their websites or give them a call.

Advisories:

• 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.
• A Blue-Green Algae Health Advisory remains in effect for Agency Lake. Agency Lake is located just north of Upper Klamath Lake near Klamath Falls along Highway 97 in Klamath County. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily.

Here is my weekly weather quiz question for the last time. What is “Accretion?” Here is the correct answer. Accretion is the growth of a precipitation particle by the collision of a frozen particle with a supercooled liquid water droplet which freezes upon impact. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer at the bottom of this page. An email will not suffice. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

Here is my weekly weather quiz question for the last time. What is “Accretion?” Here is the correct answer. Accretion is the growth of a precipitation particle by the collision of a frozen particle with a supercooled liquid water droplet which freezes upon impact. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer at the bottom of this page. An email will not suffice. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.  Good luck.

The Upper level airflow will keep the moisture pouring into the Pacific Northwest. See the frontal system that warmed us up enough to get rid of the ice and bring us more rain on the days 1-3 graphic. The graphic for days 3-7 shows a frontal system that will move toward us from the northeast. It is commonly called a “backdoor” front because it moves in from the opposite direction that fronts usually come from.  Then another frontal system is shown moving toward us from the Southwest. All of the local ski areas are open due to the repeated significant snowfalls. For mountain snow conditions check out their websites or give them a call.

Advisories:

• A WINTER WEATHER ADVISORY IS IN EFFECT UNTIL 10 AM TODAY FOR THE KLAMATH BASIN, NORTHERN AND EASTERN KLAMATH COUNTY, AND CENTRAL AND  EASTERN LAKE COUNTY.
• 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.
• A Blue-Green Algae Health Advisory remains in effect for Agency Lake. Agency Lake is located just north of Upper Klamath Lake near Klamath Falls along Highway 97 in Klamath County. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily.

• A HIGH WIND WARNING IS IN EFFECT UNTIL 1 AM FRIDAY FOR NORTHERN AND EASTERN KLAMATH COUNTY, AND CENTRAL AND EASTERN LAKE COUNTY.
• 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.
• A Blue-Green Algae Health Advisory remains in effect for Agency Lake. Agency Lake is located just north of Upper Klamath Lake near Klamath Falls along Highway 97 in Klamath County. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily.
