Graphical Tropical Weather Outlook
The Tropical Weather Outlook discusses significant areas of disturbed weather and their potential for development during the next 7 days, including a categorical forecast of the probability of tropical cyclone formation during the first 48 hours, and during the entire 7-day forecast period. The 48 h and 7-day probabilities of formation for each disturbance are given to the nearest 10% and expressed in terms of one of the following categories: low probability of development (0-30%), medium probability (40-60%), and high probability of development (70-100%).
The Tropical Weather Outlook is issued every six hours from 15 May–30 November for the Atlantic and Eastern North Pacific basins, and from 1 June–30 November for the Central North Pacific Basins at 0000, 0600, 1200, 1800 UTC.
