Pro also adds storm tracks, cones and forecast points. FORECAST Current conditions, the next hours and a daily forecast. Free shows today and the next 3 days. Pro shows all 7 days.

What’s new

Weather Bolt is the new name for HarborCast. -Storm alerts now look ahead. Pick a distance up to 1,000 miles and get an alert when a tropical storm's 5-day forecast path comes within it. The alert shows the storm's strength, how far away it is, which direction, and when it passes closest. -Storm alerts can now check in the background, so a storm in the Gulf or Atlantic can reach you before you open the app. -Tides and marine data are now optional. Turn them on in Settings if you boat, fish or paddle. -The hurricane track now draws the full line up to the storm. - New app icon.
