Lesser Antilles Antigua and Barbuda As a result of a direct hit from the Category 4 hurricane,
Barbuda experienced and over of rain, contributing to very extensive damage. According to
Lester Bird, the
prime minister of Antigua and Barbuda, most houses were damaged or eradicated at 70% in Barbuda, and nearly 45% of the residences on Antigua were damaged or destroyed by the hurricane as it passed near to the north of the island.
Guadeloupe Luis caused some damage as it passed near north of
Guadeloupe, predominantly to
Grande-Terre. Hurricane-force conditions resulted in moderate damage to homes and roofs, uprooted trees, and severe beach erosion. The
Basse-Terre region, meanwhile, received minor damage, except to banana crops that were damaged at nearly 90%, and sugar cane crops on the north at nearly 20%. Overall, of rain were recorded in the islands, while the mountain regions recorded up to . The highest rainfall within the 48-hour period was in
La Grande Soufrière, where of rain damaged the west coast roads and washed away houses. The meteorological office in
Raizet recorded sustained winds of , with gusts that reached near . The office also reported a fall in minimal pressure to between 3 and 4am on September 5, and a total of of rain across the whole period. Only
Desirade, the easternmost island, recorded hurricane-force winds of , and a sustained gust at between 3 and 4am on September 5,
Saint Barthélemy The islands suffered extensive damages from winds as the hurricane passed at least north of Saint Barthelemy. The main weather station recorded wind gust at before the anemometer broke, while other stations suggest wind speeds of and gusts of up to .
Saint Martin The eyewall of Luis passed northeast of the island of
Saint Martin, causing extensive and catastrophic damage to 60% of the area, particularly on the Dutch side. A total of of rain was recorded on the island's territory over a period of 48 hours, and the storm spawned several
F3 tornadoes.
French Collectivity In
Grand Case Bay, rough sea conditions and strong winds were responsible for the damage or destruction of 90% of homes. Other towns, such as the
French Quarter and
Marigot, also reported extensive damage to homes and vegetation. At least 50% of houses in the
Collectivity of Saint Martin were damaged, leaving between 950 and 2,000 residents homeless. The meteorological office at the
Grand Case-Espérance Airport estimated some wind gusts of over , while an unofficial
anemometer in the port of Marigot recorded wind gusts at before the instrument was toppled. One person was reported dead, and, due to lack of insurances, the preliminary cost of Luis on the French Collectivity was 2 billion francs (€300 million, or US$350 million) worth of damage.
Sint Maarten The southern part of the island, the
Dutch-owned
Sint Maarten, received more catastrophic damage than the northern
French end. The strongest winds came onshore on the Dutch side, and the capital city of
Philipsburg was at least 70% decimated by the storm. Flooding from Luis affected the
Great Salt Pond, which deluged several streets. Of the 70% of residences that were damaged in the storm, nearly 15% became uninhabitable, including businesses, churches, the main airport terminal, some schools, and four hotels. Over 5,000
Haitians living in the Dutch quarter were left homeless, while some towns on the island spent nearly three months without water and power. Of the 1,500 boats sheltered in
Simpson Bay Lagoon, nearly 1,300—or 85%—were sunken or run aground. The official death toll in Sint Maarten was eight, with the possibility of more deaths by drowning in the lagoon.
Princess Juliana Airport recorded sustained winds of , with maximum gusts of up to . The barometric pressure fell, at its lowest, between . Tropical storm-force winds brushed the island for approximately 21 hours, while hurricane-force sustained winds lasted up to eight hours as the hurricane passed with minimal forward speed between . Total damages on the Dutch side were catastrophic, totaling around US$1.8 billion, and Luis was the most devastating hurricane to hit the islands since
Hurricane Donna in 1960.
Anguilla The eye of the hurricane passed over the northeastern tip of Anguilla. Although its geographic placement means that the island likely would have sustained worse damage than St. Martin, the total scale of damage is still unknown. Luis was the worst hurricane the island suffered since
Hurricane Donna in 1960.
St. Kitts and Nevis The eye of Luis passed nearly northeast of
Saint Kitts and Nevis, causing severe beach erosion, moderate damage to residences, and leaving at least 2,000 residents homeless. The storm further damaged local vegetation and some of the road infrastructure, with problems essentially arising from the poor water system on the islands. Total damage ultimately reached $197 million.
Dominica Tropical storm-force winds of roughly affected Dominica from the morning to afternoon of September 5. The lowest pressure recorded was between . As the eye of Luis passed nearly north, the majority of the damage experienced in Dominica was inflicted upon banana crops that had already been damaged from the earlier hit by Iris. While overall damages were fairly minor, beach erosion was common, and Luis disrupted several beach hotels and coastal roads. Property damage from Luis alone was estimated at $47 million, while the combined effects of Luis, Iris, and
Hurricane Marilyn, which struck ten days later, totaled $184 million.
Puerto Rico Luis passed at northeast of
Puerto Rico, causing minor damages in the east. Two deaths were additionally reported on the island as a consequence of rushing to prepare for the arrival of the storm. High waves, in combination with high tide, caused significant beach erosion and
coastal flooding. On September 7, rip currents produced by Luis caused the death of one person near
Corncake Inlet,
North Carolina. In
Brunswick County, North Carolina, eight homes were washed away by waves, and of the beach was lost. In nearby
Hyde,
Carteret, and
Onslow counties, waves of up to washed out of the Triple S Pier in
Atlantic Beach, effectively destroying it. Total losses in North Carolina amounted to $1.9 million. In
New York, rough seas undermined and destroyed one home, and led to the death of one person who was swimming in the high waves.
Atlantic Canada On September 11, a
rogue wave triggered by Luis slammed the
Queen Elizabeth 2 ocean liner when it was about south of eastern Newfoundland. A nearby Canadian buoy recorded a at roughly the same time. Throughout eastern Newfoundland, the system dropped of rain at its landfall as a Category 1. Northwesterly winds there gusted to . One storm-related death was reported in Canada. ==Aftermath==
