Here is my new weekly weather quiz question. What is “Alluvium?”  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.

An upper level low pressure trough (Shaded “U” shape area with blue arrows) is sending more storms our way.  A frontal system will push into the Pacific Northwest today as you can see on the days 1,2 & 3 graphic with the warm front first followed by a cold front. The graphic for days 3-7 shows the typical parade of storms that bring our Autumn rain. There will be continued snow on the Cascade Passes but snow levels will continue to rise and fall. Willamette Pass has indicated they are open starting today. Hoodoo ski area plans to open Saturday December 3rd. Mt. Ashland announced Wednesday that they are starting their ski season early- this Sunday December 4th. It looks like the ski season has a good chance of starting reasonably early this year. For mountain snow conditions check out their websites or give them a call.

Advisories:

• A BEACH HAZARD STATEMENT IS IN EFFECT FROM LATE TONIGHT THROUGH SATURDAY AFTERNOON FOR THE SOUTH CENTRAL OREGON COAST AND THE CURRY COUNTY COAST. THAT MEANS LARGE BREAKERS ARE EXPECTED MOST OF THE DAY ON SATURDAY WITH HIGHEST POTENTIAL FOR DANGEROUS WAVE RUNUP ON BEACHES LATE SATURDAY AFTERNOON. JETTIES AND SURF ZONES WILL BE ESPECIALLY DANGEROUS.
• A Permanent Health Advisory remains 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 new weekly weather quiz question. What is “Alluvium?”  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.

An upper level low pressure trough (Shaded “U” shape area with blue arrows) is sending more storms our way.  The Days 1,2 & 3 graphic shows the frontal system will move through the Pacific Northwest today. The graphic for days 3-7 more frontal systems will march toward us on Saturday and late Sunday into Monday. There will be continued snow on the Cascade Passes but snow levels will continue to rise and fall. So far Willamette Pass and Hoodoo ski areas are not open. I’d say they need two good snow storms to produce the approximately 30 inches of snow they need to open. Drive carefully! If you need to travel the passes remember to be prepared to chain-up if necessary.

Advisories:

• A WINTER WEATHER ADVISORY IS IN EFFECT UNTIL 6 PM TODAY FOR THE NORTHERN OREGON CASCADES AND THE CASCADES IN LANE COUNTY.
• A WINTER WEATHER ADVISORY IS IN EFFECT UNTIL NOON TODAY FOR THE SOUTH CENTRAL OREGON CASCADES.
• A FREEZE WATCH IS IN EFFECT FROM LATE TONIGHT THROUGH THURSDAY MORNING FOR EASTERN CURRY COUNTY, JOSEPHINE COUNTY AND JACKSON COUNTY
• A Permanent Health Advisory remains 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 new weekly weather quiz question. What is “Alluvium?”  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.

________________

An upper level low pressure trough (Shaded “U” shape area with blue arrows) is sending more storms our way.  The Days 1,2 & 3 graphic shows the frontal system will move through the Pacific Northwest Wednesday. The graphic for days 3-7 more frontal systems will march toward us on Friday and late Sunday. There will be continued snow on the Cascade Passes but snow levels will continue to rise and fall. So far Willamette Pass and Hoodoo ski areas are not open. I’d say they need two good snow storms to produce the approximately 30 inches of snow they need to open. Drive carefully! If you need to travel the passes remember to be prepared to chain-up if necessary.

Advisories:

• A HIGH SURF WARNING IS IN EFFECT UNTIL 1 AM TUESDAY FOR THE NORTH OREGON COAST AND THE CENTRAL OREGON COAST.
• A HIGH SURF ADVISORY IS IN EFFECT UNTIL 10 AM TUESDAY FOR THE SOUTH CENTRAL OREGON COAST AND THE CURRY COUNTY COAST.
• A Permanent Health Advisory remains 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 an “Algorithm?” Here is the correct answer. An Algorithm is a computer program (or set of programs) which is designed to systematically solve a certain kind of problem. WSR-88D radars (NEXRAD) employ algorithms to analyze radar data and automatically determine storm motion, probability of hail, VIL, accumulated rainfall, and several other parameters. 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.

An upper level low pressure trough (Shaded “U” shape area with blue arrows) is sending more storms our way.  The Days 1,2 & 3 graphic shows the front that moved through and the next one coming on Monday. The graphic for days 3-7 shows the next series of fronts that we will see approaching Wednesday and for next weekend. There will be snow on the Cascade Passes for through the rest of the weekend into next week, BUT so far Willamette Pass and Hoodoo ski areas will not be open. I’d say they need two good snow storms to produce the approximately 30 inches of snow they need to open. Drive carefully! If you need to travel the passes remember this is the first real snow of the season and you will have to be prepared to chain-up if necessary.
