Individual waves may be more than twice the significant wave height. PMZ001-212115- Synopsis for the E Pacific within 250 nm of Mexico 204 AM PDT Sat Aug 21 2021 .SYNOPSIS...Tonight, winds across the Baja California and SW Mexico offshore waters will increase to moderate to fresh ahead of the remnant low of Hurricane Grace, which is expected to weaken to a tropical storm near 20.2N 99.6W this afternoon, move farther inland and weaken to a tropical depression near 20.1N 101.6W Sun morning, and dissipate Sun afternoon. The remnants of Grace will emerge over the eastern Pacific Ocean off the west- central coast of Mexico on Sun afternoon where environmental conditions may favor the development of a tropical depression by early next week while the system moves westward away from the coast of Mexico. Regardless of development, strong winds and building seas will affect the offshore waters of Colima, Nayarit, and Baja California Sur Sun through Tue. Another area of low pressure is forecast to form offshore of the coast of southern Mexico early next week with the potential to become a tropical depression by the middle of next week. $$ PMZ009-212115- Mexico Border S to 29N within 60 nm of shore- 204 AM PDT Sat Aug 21 2021 .TODAY...Variable winds less than 5 kt, becoming W 10 kt in the afternoon.
