There are two mosquito transmitted diseases (virus), Dengue, and Chikungunya Fever, now in the Caribbean. Both viruses are transmitted by Aedes species mosquitoes, which have black and white stripes markings. Please take a look at link information. More »
The Tradewinds (the Easterlies) dominate the weather in the Virgin Islands, blowing east to west across the tropical Atlantic. The winter tends to bring stronger winds and less rain, and the summer tends to bring more rain and lighter winds.
In winter, cold fronts moving off the continent sometimes bring the Christmas winds down from the north. The fronts do not bring cold air as far south as the Virgin Islands, but they can create large waves breaking on the north shore beaches. Use extreme caution entering the water during such conditions, and heed posted warnings and advice from park staff.

The mangrove forests found along the coastline in some bays serve as nursery habitats for juvenile fish. These beautiful trees with aerial roots provide filtration of the runoff and reduce the amount of sediment reaching the ocean. The Red Mangrove is one of several species found in the Park.
