Tropical Weather Outlook

Atlantic:
Tropical cyclone formation is not expected during the next 48 hours.

Western Pacific: 
No activity.

Eastern Pacific:
Shower and thunderstorm activity continues to become better organized in association with a broad area of low pressure located about 160 miles south-southeast of Acapulco, Mexico. Conditions appear favorable for further development and a tropical depression could form in the next day or so as this system moves slowly west-northwestward. There is a high probability, greater than 50 percent, of this system becoming a tropical cyclone during the next 48 hours. Regardless of development, heavy rains associated with this system could affect portions of the southern coast of Mexico during the next few days.

Disorganized showers and thunderstorms continue in association with a broad area of low pressure located about 1,600 miles southwest of the southern tip of Baja California. Development of this system, if any, will be slow to occur as it moves slowly eastward over the next couple of days. There is a low chance, less than 30 percent, of this system becoming a tropical cyclone during the next 48 hours.

Elsewhere tropical cyclone formation is not expected during the next 48 hours. (NOAA, HPC, National Hurricane Center, Central Pacific Hurricane Center and the Joint Typhoon Warning Center)
