The center said swells generated by Norma will begin affecting portions of the coast of southwestern Mexico and Baja California Sur on Saturday and continue into early next week.
Max had maximum sustained winds of 80 mph (130 kph), was located about 55 miles (90 kilometers) east-southeast of Acapulco and was heading toward the east at 8 mph (13 kph), the hurricane center reported. Norma was moving toward the north near 5 miles per hour (7 kph), and this general motion at an even slower forward speed is expected to continue through early Saturday.
The path of Norma remains uncertain: the position and strength of pressure systems in the area could impact its track. At this point Norma will be weakening due to increased vertical wind shear and land interaction.
Tropical Storm Norma is the newest addition to the tropical cyclones in the Eastern Pacific and NASA’s Terra satellite caught it after it developed. This is the forecast favored on balance by the NHC, who predict a tropical storm-force landfall early UTC on Tuesday September 19.
Even if Norma does not eventually impact land, risky surf and rip current conditions are expected this weekend along the coast of southwestern Mexico and Baja California Sur. Norma is a slow-moving storm and is likely to bring sustained rain to Baja California, creating risks of flash flooding, regardless of landfall timing.
