1 THE ATLANTIC HURRICANE SEASON SUMMARY – 2009 ANTIGUA AND BARBUDA, THE LEEWARD ISLANDS AND THE BRITISH VIRGIN ISLANDS

2 The 2009 hurricane season had been relatively quiet for most countries in the Eastern and Western Caribbean. It would appear that the el Nino event and its impacts on the hurricane season generally held true, especially in the Western Caribbean. The Northeast Caribbean including Antigua & Barbuda and the Leeward islands experienced a number of threats from most of the storms/hurricane that developed in the Atlantic but apart from heightened excitement and some needed rainfall, not much activity was recorded
