HurriMap: Hurricane and Typhoon Tracker When a storm is coming, every hour matters. HurriMap shows where it could go, when damaging winds could reach you, and when to be finished preparing. It's personal hurricane decision support: the official forecast, turned into a timeline for your own place. KNOW WHEN TO PREPARE • Enter the hours you need to get ready and see your "finish preparations by" time, built from the earliest reasonable arrival of tropical-storm-force winds. • See the earliest reasonable and most likely arrival of 39, 58 and 74 mph winds, drawn as labeled contours on the map. • Check your chances of damaging winds, whether you're in the cone, and how close the center will pass. Dangerous conditions can extend well beyond the cone. FOLLOW EVERY STORM • Hurricanes, tropical storms and developing systems in the Atlantic, Gulf of Mexico, Caribbean, and eastern and central Pacific, including Hawaii. • NEW: Typhoons and South Pacific cyclones for Guam, the Northern Mariana Islands and American Samoa, with track, wind field, danger area, models, wind chances and arrival times. • Forecast tracks, the cone of uncertainty, storm history, wind fields, and coastal and inland watches and warnings. • Two-day and seven-day formation chances for developing systems. • National Hurricane Center advisories, discussions, key messages and hazards, and Joint Typhoon Warning Center warnings, reflowed for your phone. • Infrared, visible and water vapor satellite imagery.
