1. Introduction The British Caribbean Territories were particularly hard hit by the 2017 Hurricane Season. Hurricane Irma impacted on Anguilla, the British Virgin Islands and the Turks and Caicos Islands, while Hurricane Maria added to the woes in the Turks and Caicos Islands. 2. Hurricane Irma The centre of Hurricane Irma passed within 7.5 miles (12km) of the nearest point of the southwestern tip of Anguilla on the morning of 6 September and Figure 1 shows that Anguilla experienced the effects of the passage of the eyewall. Figure 1: Satellite image showing the proximity of the centre of Irma to Anguilla. Data was retrieved from an automatic weather station located at the Clayton J. Lloyd International Airport in Anguilla, at latitude 18°12'20.20"N and longitude 63°03'15.23"W at a height of 30 meters above mean sea level. This showed that between 0630UTC to 1600UTC, 345.8 mm of rainfall was measured with the highest 10 minute totals occurring between 1040UTC to 1120UTC. Figure 2 is a graph of the 10 minute rainfall for the time period mentioned above. Figure 2: 10-minute rainfall totals in millimeters. Although the center of Irma did not pass over Anguilla, the island recorded a 10-minute average wind speed of 165.4kt at 1400UTC. Figure 3 shows the average 10-minute for the period 0630UTC to 1600UTC. The lowest barometric pressure measured as shown in Figure 4. Figure 3: 10-minute average wind speed Figure 4: Barometric pressure as read by the AWS The damage caused by Irma in Anguilla was extensive; the southern and western sides of the islands suffered the worst of the damage. The island lost electrical power because of damage to the infrastructure, approximately 98% of the housing stock was damaged, and there was one death. The Government of Anguilla estimated that the total cost of physical damage was USD 290 million. Figure 5, shows some of the damage which occurred in Anguilla.
