ZCZC MIATWOEP ALL TTAA00 KNHC DDHHMM Tropical Weather Outlook NWS National Hurricane Center Miami FL 1100 PM PDT Tue Aug 20 2024 For the eastern North Pacific...east of 140 degrees west longitude: The National Hurricane Center is issuing advisories on Tropical Storm Gilma, located several hundred miles west-southwest of the southern tip of the Baja California peninsula. Well East-Southeast of the Hawaiian Islands (EP90/EP91): Showers and thunderstorms associated with a well-defined area of low pressure located well east-southeast of the Hawaiian Islands are gradually becoming better organized, and only a slight increase in organization could result in the formation of a tropical depression or tropical storm while it moves generally westward at 10 to 15 mph. The weaker disturbance located just to its southwest is expected to dissipate or merge with this system during the next several hours. This system is expected to strengthen as it moves across the central Pacific basin late this week and move near the Hawaiian Islands late this weekend or early next week. 1. While it is too early to determine the exact location and magnitude of potential impacts, interests in Hawaii should closely monitor this disturbance. Information on this system's development can also be found in the Tropical Weather Outlook for the Central Pacific basin. For marine forecasts, including gale warnings, see High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...high...90 percent. * Formation chance through 7 days...high...90 percent. 2. Eastern and Central Portion of the East Pacific: Disorganized showers and thunderstorms centered several hundred miles southwest of the coast of southwestern Mexico are associated with a trough of low pressure. Environmental conditions are forecast to become more conducive for development in a day or two, and a tropical depression could form late this week or over the weekend while the system moves west-northwestward over open waters, well offshore of Mexico. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...medium...60 percent.
