Hurricane Seymour will remain a Category 4 hurricane through much of the day today, as it will remain in an area with low wind shear and very warm ocean water. Weakening will commence by this evening as it starts to encounter lower sea surface temperatures. Rapid weakening is expected Thursday into Friday as it turns northwest into an area of stronger wind shear. Seymour will weaken to a tropical depression Friday night or early Saturday morning then dissipate on Sunday.
Seymour is not going to have any direct impacts on land, but increased surf and strong rip currents will continue to impact the west coast of Mexico through the weekend. Some of Seymour's moisture will be drawn northward into an approaching storm that is forecast to move into California Thursday into Friday. Locally heavy downpours and isolated flash flooding will be likely across parts of California.
Additional tropical development across the eastern Pacific is not expected through this weekend.
