Deaths Associated with Hurricanes Marilyn and Opal -- United States, September-October 1995

The 1995 hurricane season was one of the most severe in U.S. history and included 11 hurricanes. During a 2-week period, the two most damaging storms -- hurricanes Marilyn and Opal -- made landfall in the United States. To characterize the deaths attributed to these storms, CDC contacted medical examiners/coroners (ME/Cs) in the affected areas. This report summarizes the findings of these investigations.

Hurricane-related deaths can occur before (preimpact), during (impact), and after (postimpact) a hurricane strikes land. Deaths determined by local ME/Cs to be "disaster-related" are those directly (i.e., resulting from the environmental force of the hurricane) or indirectly (i.e., death caused by an injury or illness associated with hurricane-related events such as evacuation, clean-up, or loss of electricity {1}) related to the storm.

Hurricane Marilyn, September 1995

On September 15, Hurricane Marilyn, a category two (on a scale of one to five) storm with sustained winds of 105 mph, made landfall in the U.S. Virgin Islands (USVI). The hurricane passed directly over St. Thomas (1990 population: 48,166) and affected St. John (1990 population: 3504) and St. Croix (1990 population: 50,139) in the USVI, and the islands of Culebra (1990 population: 1542) and Vieques (1990 population: 8602) in the Commonwealth of Puerto Rico (Figure_1). Gale-force winds, heavy rains, and storm surges of 3-5 feet resulted in damages reported at approximately $3 billion; more than 80% of the residential dwellings in St. Thomas were damaged or destroyed (2).

ME/C offices in the USVI and the Institute of Forensic Sciences in Puerto Rico provided information about hurricane-related deaths reported from September 15 through October 4. Specific information included characteristics about decedents (e.g., age and sex) and the circumstances of death (e.g., date of injury, date of death, location, cause of death, and other circumstances).

ME/Cs reported 10 deaths that were related, directly or indirectly, to Hurricane Marilyn (Table_1). The mean age for the seven decedents whose ages were known was 56.5 years (range: 17-107 years); eight were male. Of these 10 deaths, six were reported by the ME/Cs from St. Thomas and St. John, two from St. Croix, and two from Puerto Rico.

One death occurred preimpact; the other nine occurred during the impact phase of the hurricane. The preimpact death occurred in Puerto Rico when the decedent was electrocuted while moving a TV antenna in preparation for the storm. Eight of the deaths, including the second death in Puerto Rico, were boat-related (i.e., the victims were on boats when the hurricane struck). Drowning was reported as the cause of seven of these boat-related deaths; head trauma was reported as the cause of one death. A 107-year-old woman died in an emergency shelter in the USVI; her death, although possibly precipitated by the circumstances of the hurricane, was attributed to natural causes.

Hurricane Opal, October 1995

On October 4, Hurricane Opal, a category three storm with sustained winds of 115 mph, moved across the Gulf of Mexico and made landfall approximately 20 miles east of Pensacola, Florida. Gale-force winds and storm surges of 10-15 feet caused severe damage throughout the panhandle of Florida; the coastal areas were affected most severely (M. Mayfield, National Hurricane Center, personal communication, 1995). Although the hurricane was downgraded to a tropical storm (i.e., sustained wind speeds of 39-74 mph) soon after landfall, accompanying heavy rains and high winds caused extensive damage as the storm moved northward across southern and northeastern Alabama, through northwestern Georgia, and into North Carolina (Figure_2). In addition to the seven counties in Florida that were initially declared federal disaster areas, disaster declarations also had been issued for 37 counties in Alabama, 47 counties in Georgia, and 13 counties and the eastern band of the Cherokee Reservation in North Carolina (3).

Data on deaths reported during October 4-25 attributed to the storm were provided by the offices of the ME/Cs in all counties in Alabama, Florida, and Georgia for which state or federal disaster declarations were issued, and in other counties without disaster declarations where hurricane-related deaths were reported; in addition, CDC contacted counties adjacent to those meeting the above criteria. In North Carolina, the chief ME in the State Department of Environment, Health, and Natural Resources was contacted for information on the entire state. ME/Cs were asked to provide information about decedents and circumstances of any death attributed to the hurricane. All eligible counties except one in Alabama and one in Georgia were contacted.

A total of 27 hurricane-related deaths were reported by the ME/Cs: two deaths occurred in Florida, 12 in Alabama, 11 in Georgia, and two in North Carolina. Of these, one occurred during the preimpact phase of the storm, 13 during the impact phase, and 13 during the postimpact phase. Decedents ranged in age from 4 years to 87 years, and 21 were male. For the 26 decedents aged 20-87 years, the mean age was 52.4 years.

Of the 27 deaths, the cause of death for 24 was considered accidental *; the other three deaths were attributed to natural causes but were considered hurricane-related because circumstances created by the hurricane contributed to the deaths. One death resulted from exacerbation of chronic obstructive pulmonary disease following strenuous activity during clean-up activities, and two deaths resulted from myocardial infarctions that also were attributed to strenuous clean-up activities.

Thirteen deaths were related to falling or fallen trees; of these, nine occurred during the impact phase when victims were struck by trees falling on or near their residence (six), place of employment (one), or motor vehicle (two). Three occurred when vehicles struck trees lying in the road, and one occurred when the decedent was struck while cutting down a tree that had partially fallen during the storm.

Four deaths were attributed indirectly to power outages: one death from carbon monoxide poisoning associated with the use of a gas generator and three from house fires started by candles (two) or a propane cooking device (one). Motor vehicles were implicated in seven of the deaths, including persons in motor vehicles that were struck by falling trees or that ran into downed trees (five). Five other deaths occurred during the postimpact phase: one person drowned in a swollen creek; one was electrocuted while repairing a downed power line; one sustained massive chest trauma after a tractor overturned; and two suffered heart attacks while repairing damage and clearing debris.

Editorial Note

Editorial Note: Before Hurricane Hugo in 1989, most hurricane-related deaths occurred during the impact phase, usually along the coastline, and were attributed to drowning from hurricane-related storm surges. For example, following Hurricane Camille, which struck the Gulf of Mexico coast in 1969, most of the 256 storm-related deaths were attributed to drowning that resulted from 25-foot storm tides near the coast and flash floods further inland (4). Since then, however, improvements in forecasting technology and evacuation procedures have decreased the number of deaths attributed to drowning from storm surges during recent hurricanes (5). Consequently, an increasing proportion of deaths occurring during the impact phase of recent hurricanes have been attributed to the effects of the high winds rather than storm surges (1). In addition, since Hurricane Hugo, the proportion of deaths that occur during the postimpact phase has increased. Many of these deaths and nonfatal injuries result from electrocutions from contact with downed power lines, chain saw lacerations, and trauma from falling trees (6,7).

During Hurricane Marilyn, no deaths directly related to the impact phase of the storm occurred on any of the islands, possibly reflecting the effectiveness of measures to evacuate and shelter the population at risk. However, eight of nine persons who died during the impact of the storm were at sea at the time of death, suggesting that warnings should be strengthened to emphasize risks of being aboard a vessel during a hurricane. In USVI and other areas where substantial numbers of persons reside on boats, these persons should be encouraged to evacuate to shelters on land.

Many of the deaths attributed to Hurricane Opal occurred among persons in inland counties after the hurricane had been downgraded to a tropical storm, suggesting that persons in these areas may not have recognized or been fully informed about the risks associated with severe storms. In particular, because the use of motor vehicles during and after the storm was associated with several deaths, risks related to driving during or immediately following a severe storm should be emphasized, and persons should be encouraged to remain off the roads. In addition, because many deaths occurred after the storm during surveying efforts or clean-up activities, emergency notifications should stress the persistent risks of environmental hazards (e.g., downed trees and power lines) even after the storm has passed.
