HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions, primarily in gusts, are expected within the tropical storm warning areas through this morning. SURF: Swells generated by Jose are affecting portions of the Leeward Islands, the Virgin Islands, and the northern coast of Puerto Rico, and will begin to affect Hispaniola, portions of the Bahamas, and the Turks and Caicos Islands over the next couple of days. These swells are likely to produce life-threatening surf and rip current conditions. Please consult products from your local weather office.
