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.

Guy Carpenter today released Part One of a two-part series report detailing a ten-year retrospective on the 2004 and 2005 Atlantic Hurricane Seasons - two landmark years that were not only significant for their weather events, but for their lasting effects on the (re)insurance industry. The report examines the meteorological conditions that contributed to the weather activity characterizing both hurricane seasons, as well as the impact on underwriting and claims adjusting practices, cat modeling, and the Florida Hurricane Catastrophe Fund (FHCF).
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.
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).
