Tropical Waves in the Eastern Atlantic

As hurricane season is now in full swing, tropical waves are developing in the Eastern Atlantic. According to the National Hurricane Center, a tropical wave is “A trough or cyclonic curvature maximum in the trade-wind easterlies. The wave may reach maximum amplitude in the lower middle troposphere.” 

There are currently two tropical waves in the Eastern Atlantic. The first is located about 650 miles west from the Cape Verde Islands and has around a 10% chance of forming into something stronger. The second tropical wave is currently sitting right off the west coast of Africa. This wave is expected to strengthen as it continues to move to the west/northwest; formation chance in the next 48 hours is 30%, 60% in the next five days.

The peak season for hurricanes is mid-August to late October, as atmospheric and oceanic conditions are most favorable for the formation of hurricanes during this time. The African Easterly jet, warm sea temperatures, and a lack of deep layer wind shear all contribute to the peak of tropical storm and hurricane formation during these months (The Weather Channel).
