Here is my weekly weather quiz question for the last time. What is “The National Hurricane Center”? Here is the correct answer. National Hurricane Center is one of three branches of the Tropical Prediction Center (TPC). This center maintains a continuous watch on tropical cyclones over the Atlantic, Caribbean, Gulf of Mexico, and the Eastern Pacific from 15 May through November 30. The Center prepares and distributes hurricane watches and warnings for the general public, and also prepares and distributes marine and military advisories for other users. During the “off-season” NHC provides training for U.S. emergency managers and representatives from many other countries that are affected by tropical cyclones. NHC also conducts applied research to evaluate and improve hurricane forecasting techniques, and is involved in public awareness programs.

An Upper Level Low Pressure Trough still sits off the West Coast. Meanwhile wildfire smoke can still push into the Pacific Northwest from various areas depending on the wind direction. The graphics for days 1-3 show a cold front off the Oregon coast Sunday. The graphics for days 3-7 Tuesday through Saturday show a frontal system will be moving southward along the California coast then sliding through Oregon Tuesday.
