[QUOTE="WPLG, post: 55244, member: 158"] A robust tropical wave – a ripple in atmospheric winds 5,000 to 10,000 feet up triggering a large area of showers and thunderstorms – is emerging today off the coast of Africa. We’ll be tracking this disturbance during the week for potential organization as it moves westward through the Atlantic. For now, the environment ahead looks only marginally favorable for development, primarily over the eastern Atlantic. Forecast models aren’t keen on doing very much with it at this point, especially with conditions becoming increasingly hostile by next weekend. The biggest prohibitive factor for development will be a very stable tropical Atlantic, much more so than usual for this time of year. This, combined with a dry middle atmosphere, should limit thunderstorm growth around the system.
