Hurricane Gonzalo is now a dangerous Category 3 hurricane on the Saffir-Simpson scale and is expected to make a close approach to Bermuda, with closest approach this evening. Model guidance is in close agreement on this scenario. Gonzalo will be the strongest hurricane to affect Bermuda since Hurricane Fabian (2003), also a Category 3. Tropical storm winds are already affecting the island of Bermuda, and the onset of hurricane conditions is expected this afternoon. A significant surge event can be expected with battering 30 foot waves.
Hurricane Gonzalo is forecast to make a direct hit or close approach to Bermuda sometime on Friday, most likely as a Category 3 hurricane on the Saffir-Simpson scale. Hurricane and tropical storm force winds extend outward up to 45 miles (75 kilometers) and 150 miles (240 kilometers) from the center of circulation, respectively. After clearing Bermuda, Gonzalo should eventually make landfall in Eastern Atlantic Canada as a strong post-tropical cyclone.
Hurricane Odile made a direct hit to the Southern end of the Baja Peninsula, Mexico, Sunday night, with impacts of great severity. Maximum sustained winds at landfall were 125 mph, a Category 3 hurricane on the Saffir-Simpson scale, according to the National Hurricane Center (NHC). Odile is now a tropical storm and poses an ongoing threat of wind, surge and especially heavy rain. The wind impacts of Odile include severe to complete damage to hundreds of homes, with severe damage to hotels and the Los Cabos airport. Downed trees and power lines are widespread, and power outages have affected at least 200,000. According to the NHC, Odile is tied with Olivia, which struck in 1967, as the strongest hurricane to make landfall in the state of Baja California Sur.
Tropical Storm Iselle made landfall at about 2:30 a.m. HST (1230 UTC) today along the Kau Coast on the Big Island, according to the Central Pacific Hurricane Center (CPHC). Maximum sustained winds at landfall were 60 mph, with higher gusts especially at higher elevations. Iselle was moving slowly leading to excessive rainfall accumulations. Resulting flooding has been extensive, together with reports of downed trees and power lines for affected areas. Roads are blocked with debris and downed trees, and power outages have affected at least 33,000. Some roof damage has been reported. There are no reports of deaths or major injuries.
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.

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).
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).
