• A slight risk of high winds for portions of western Mainland Alaska, Wed-Thu, Oct 23-24.

• Possible flooding for the northern and central Florida Peninsula.

• Risk of Rapid Onset Drought (ROD) across portions of eastern Texas, northern Louisiana, and southern Arkansas.

• Snowfall for parts of Canada and the risk of a growing season-ending frost/freeze for Ontario and Quebec.
