HURRICANE TRACKING ADVISORY eVENT™ Hurricane Joaquin Information from NHC Advisory 25, 5:00 PM EDT Saturday October 3, 2015 On the forecast track, the eye of Joaquin will pass west of Bermuda on Sunday. However, a small deviation to the east of the forecast track would bring the core of the hurricane and stronger winds closer to Bermuda. Maximum sustained winds are near 150 mph with higher gusts. Joaquin is a strong category 4 hurricane. Some fluctuations in intensity are likely tonight, but Joaquin is forecast to gradually weaken during the next 48 hours. Intensity Measures Position & Heading U.S. Landfall (NHC) Max Sustained Wind 150 mph Position Relative to 500 miles SW of Bermuda Speed: (category 4) Land: Est. Time & Region: n/a Min Central Pressure: 934 mb Coordinates: 27.0 N, 70.5 W Trop. Storm Force Est. Max Sustained Wind 205 miles Bearing/Speed: NE or 45 degrees at 17 mph n/a Winds Extent: Speed: Forecast Summary The current NHC forecast map (below left) shows Joaquin approaching Bermuda at hurricane strength. The windfield map (below right) is based on the NHC’s forecast track and also shows Joaquin approaching Bermuda at hurricane strength. To illustrate the uncertainty in Joaquin’s forecast track, forecast tracks for all current models are shown on the map in pale gray. Tropical storm conditions are first expected to reach Bermuda by Sunday morning, with hurricane conditions possible by Sunday afternoon. Outer rain bands of Joaquin will begin to affect Bermuda by early Sunday, and Joaquin is expected to produce 3 to 5 inches of rainfall over Bermuda through Monday. Swells generated by Joaquin will continue to affect portions of the Bahamas during the next few days. Swells are affecting much of the southeastern coast of the United States and will spread northward along the east coast of the United States through the weekend. Swells from Joaquin will begin affecting Bermuda today and continue through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Even though Joaquin is expected to pass well east of the coast of the United States, a prolonged period of elevated water levels and large waves will affect the mid-Atlantic region, causing significant beach and dune erosion with moderate coastal flooding likely.

There both peak in September, as the graph below illustrates. The average are currently two regions in the Atlantic where tropical cyclone remaining percentage of days with Atlantic hurricane activity at Oct 3 is formation is possible within the next 48 hours – both east of 19% for all hurricanes and 14% for major hurricanes.
