Hurricane Andrew made U.S. landfall in 1992. The storm originated from a tropical wave and experienced disruptive wind shear until arriving in the West Atlantic. Once in the West Atlantic, Andrew first reached hurricane status on the morning of August 22 and then developed explosively into a Category 5 hurricane on the Saffir-Simpson scale with maximum sustained winds of 165 mph when it made landfall on Florida’s coast.
The chart indicates that the proportion of hurricanes counted in the Atlantic Basin and those that made landfall has been very volatile through the years. While there is indeed a weak correlation between hurricane counts in the Atlantic Basin and the number of U.S. landfalls, statistical significance is a subject of some debate in the scientific community (Coughlin et al., 2009; Dailey et al., 2009).

Any hurricane can produce wind, surge and inland flood impacts. The severity and scope of impacts is not always consistent with ratings on the Saffir-Simpson scale, particularly for surge as we have seen with Katrina (2005) and Sandy (2012).

The El Niño phenomenon is signaled by warmer than normal sea surface temperatures (SSTs) in the tropical East Pacific. The large-scale circulations associated with El Niño enhance wind shear (changing wind speed with height) in the tropical Atlantic. The enhanced wind shear disrupts tropical cyclone formation, generally associated with fewer tropical cyclones in the Atlantic Basin. The suppressing effects of El Niño are found to be strongest in the deep tropics (Kossin et al., 2010).
Hurricane Arthur is the first hurricane to make U.S. landfall since 2012, and the earliest to make North Carolina landfall for any hurricane season since 1908. According to the National Hurricane Center (NHC), Arthur made landfall in North Carolina on July 3 at about 11:15 p.m. EDT (0315 UTC), with maximum sustained winds of 100 mph (161 km/hr).
Hurricane Arthur was reclassified as a hurricane overnight by the National Hurricane Center (NHC), and currently carries maximum sustained winds of 90 miles per hour. Arthur is currently moving offshore of the U.S. mainland to the north-northeast at about 10 miles per hour. Hurricane and tropical storm force winds extend outward from the center of circulation to 25 and 115 miles, respectively.
Tropical Storm Arthur, the first named storm of the 2014 Atlantic hurricane season, is expected to reach hurricane strength Thursday, according to the National Hurricane Center (NHC). Arthur is currently located 110 miles east-northeast of Cape Canaveral, Florida and 235 miles south of Charleston, South Carolina. The storm is moving north at seven miles per hour and is expected to turn toward the north-northeast Wednesday night. By Thursday, the storm is expected to turn toward the northeast with an increase in forward speed. The eye of Arthur is expected to pass east of Northeastern Florida tonight and move parallel to the coasts of South and North Carolina during the next 24 to 48 hours.
