'Catastrophic' Hurricane Earl heads for US coast
A storm moving through the eastern Caribbean has strengthened to a category four hurricane, prompting warnings for several islands.
Hurricane Earl is expected to gain more strength before heading towards the US. Forecasters say it is a major hurricane and could cause "catastrophic" damage if it hits land.
Strong winds and heavy rains are already lashing several islands in the Caribbean, but the storm has now passed by the Virgin Islands. The hurricane is generating winds of 215km/h.
