This Art Form Has Found A Resurgence Recently.

Here is my weekly weather quiz question for the last time. What are “Detention Basins?”  And no, this has nothing to do with staying after school. Here is the correct answer. Detention Basins are structures built upstream from populated areas to prevent runoff and/or debris flows from causing property damage and loss of life. They are normally dry, but are designed to attenuate storm flows or detain mud/debris during and immediately after a runoff event. They have no spillway gates or valves and do not store water on a long-term basis. Typical detention times for storm flows are on the order of 24 to 72 hours, but may be as long as 5 to 10 days. Basins designed for detention of mud and rock debris are periodically excavated to maintain their storage capacity.  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.

An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) takes over for the rest of the weekend, then an Upper Level Low Pressure Trough (Shaded “U” shape with arrows) moves in sending moisture filled storms out way. The graphics for days 1-3 show the break from active weather. The graphics for days 3-7 show the next frontal systems that will be moving through the Pacific Northwest next Tuesday through Saturday.

Note: Willamette Pass Ski is closed for the season due to a lack of snow, but Hoodoo is open Thursday through Sunday from 9 AM- 4 PM or 9 PM. Mt. Ashland is open and reports all lifts are operating. They will also be open 9 AM until 4 pm March 24th through April 1st for Spring break. Check their websites for details on days of operation and ski conditions.

Note: Daylight Saving Time began at 2 AM so I hope you remembered to “Spring Forward!” last night  by turning your clocks ahead one hour. The authorities also suggest that you check the batteries in your smoke alarms, CO2 detectors, and Radon detectors and replace them if necessary. If you forgot it’s not too late to catch up with the rest of us.
