Tropical Depression Six became the main Atlantic system under watch, while forecasters also flagged multiple potential trouble spots across the Pacific.
Tracker maps highlighted the main factors shaping development: sea-surface temperatures, wind shear and dry Saharan air, with strong shear and dust-laden air limiting storm growth.
Atlantic season maps also showed the tracks of all systems that have already reached at least tropical or subtropical storm strength this year.
Pacific monitoring included spaghetti models, sea-surface temperatures, season-to-date storm tracks and accumulated cyclone energy, a gauge of how active the season has been.
