A Kelvin wave (KW) is forecast to propagate eastward over the Western Hemisphere during the next week. This KW is expected to reduce vertical wind shear and provide a favorable large-scale environment for tropical cyclone (TC) development across the East Pacific and/or the western Caribbean Sea and Bay of Campeche. A number of GFS and Canadian ensemble members continue to feature TC development near the Yucatan Peninsula with potential tracks north into the Gulf of Mexico, as early as next week. Although model spread is large with TC genesis and its potential future track, a slight risk of heavy rainfall is maintained for southern Florida through Week-2. Depending on future model runs, the slight risk of heavy rainfall may need to be expanded north to cover more of the Gulf Coast.
