Late on August 12, a strong tropical wave associated with an area of low pressure moved off the African coast with deep layers of moisture observed.[1] Later that day, the wave became better organized with a low level circulation forming, but without any significant convection. That night, the area of convection became more concentrated, but wind shear increased since the previous advisory. On August 14, the disturbance strengthened more and its convective bands became stronger with better circulation, indicating that the disturbance would soon become a tropical depression. Later, on August 15, even though some of its deep convection dissipated, it was officially named Bill, the second named storm of the 2009 season. Early on August 17, an eye appeared on visible and infrared loops and Bill strengthened into a hurricane, the first of the 2009 season. Bill then briefly underwent an eyewall replacement cycle, as the eye had contracted to a half its original size. However, strengthening continued and on the evening of August 18, and Bill rapidly strengthened into a major hurricane. Current computer model forecasts are showing a possibility of Hurricane Bill or its remnants making landfall in Atlantic Canada early next week.[2]
