Norma lost its tropical characteristics and degenerated into a remnant low pressure center late Tuesday evening. The system continues to track west away from the Baja Peninsula over cooler water, preventing regeneration into a tropical depression or tropical storm. The only impacts to land will be rough surf and high seas along the Baja California and Mexican coast.
Aside from Norma, there is one other area across the East Pacific we are currently monitoring for potential tropical development. An area of low pressure will develop later this week south of the southern coast of Mexico. This low will then track west-northwestward through a zone of low wind shear and warm ocean waters. Thus, by late this week or the upcoming weekend, further development and organization of this system will be possible.

000 ABPZ20 KNHC 201721 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 1100 AM PDT Wed Sep 20 2017 For the eastern North Pacific...east of 140 degrees west longitude: A broad area of low pressure located a couple of hundred miles east-southeast of Acapulco near the coast of Mexico is producing disorganized showers and thunderstorms. Land interaction should limit development of this system during the next day or two, but a tropical depression will likely form over the weekend when the system moves farther offshore. Regardless of tropical cyclone formation, heavy rains are expected over portions of southern Mexico during the next several days. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...high...80 percent. $$ Forecaster Cangialosi
