Potential for High Winds Oct. 24-26 with Heavy Rain Oct. 24
KEY POINTS
• A moderate atmospheric river and quick-following low pressure system brings multiple rounds of widespread rain and chances for high winds across northwest Oregon, southwest Washington, and the coastal waters Oct. 23-26.
• Inland: 20-30% chance for a moderate impact wind event (mainly Saturday) with max wind gusts over 45 mph for inland areas. However, less than a ~10% chance for a high impact wind event with max wind gusts over 55 mph for inland areas.
• Coast: 45-80% chance for a moderate impact wind event with max wind gusts over 45 mph for coastal areas (Friday and Saturday, Oct 24-25) and a 50-70% chance for a high impact wind event with max wind gusts over 55 mph (mainly Saturday, Oct 25).
• Highest winds overall expected on Oct. 25. If wind gusts around the moderate (>45 mph) to high (>55 mph) impact level do materialize, widespread tree damage and power outages would occur.
• Coastal waters: 10-35% chance for storm force wind gusts of 48 kt or stronger into Friday morning (Oct 24). Probabilities for Storm Force wind gusts closer to 40-65% on Saturday, Oct 25. The highest probabilities for both periods of time are over the northern Oregon and southern Washington inner waters.
• Heavy rainfall rates may cause flooding of urban, low-lying, or other poor-drainage areas. There is a 25% chance rainfall rates exceed 0.25″ per hour Friday afternoon and evening (12 PM Oct 24 to 12 AM Oct 25), a rate threshold that typically corresponds to nuisance flooding or widespread ponding on roadways. There is also a 15% chance rainfall rates exceed 0.5″ per hour, most likely from 5-10 PM Friday evening (Oct 24). This rate threshold corresponds to more severe urban flooding of areas which are not typically inundated during more typical rain events. These elevated rainfall rates are equally likely in more rural areas, however impacts on the ground would likely be lessened.
• River flooding is unlikely (<5% chance), as river levels are currently at or near their annual minimum and should be able to handle the expected runoff.
• Coast: Seas of 20-25 ft expected Saturday into Sunday morning. Breakers of 30 ft likely during this time.
• Moderate to high Sneaker Wave threat likely continues through the weekend. Sneaker waves can suddenly knock people off of their feet and quickly pull them into the ocean which may lead to serious injury or drowning.
• Make sure to secure outdoor items which could be blown away by strong winds. Clear your gutters and drains of leaves and other debris to ensure proper drainage during heavy rain.
• Travel impacts from snow in the Cascades are not expected Thursday night-Friday (Oct 23-24), as snow levels will likely be above the passes (70-90% chance). Snow levels likely fall to 3500-4500 ft Saturday night into Sunday (Oct 25-26), bringing accumulating snow at pass level with over 6 inches of snow likely at pass level (80-90% chance).
