The first 60 days of the Atlantic Hurricane season are coming to an end. On 30 July 2011 there are plenty of signs of potential cyclonic activity throughout the northern hemisphere tropics. On the satellite image above we can clearly see a large tropical wave in the Caribbean off the Nicaragua-Honduras border, also one large tropical wave that is showing signs of organization and further strengthening to the east of the Lesser Antilles in ‘Hurricane Alley’ followed by another tropical wave to the east.

Farther to the east over the eastern Atlantic and equatorial Africa we see the ‘Tropical-wave assembly line’ has gotten much better organized over the past couple of weeks and it is now showing regularly spaced pulses of tropical weather activity that will become tropical waves feeding into ‘Hurricane Alley’.

These satellite images gives us evidence that appear to indicate the northern tropics are finally organizing into a pattern of activity that is typical of the historically most active months, August-September and October, of the Atlantic hurricane season. On this day, for the first time in a while, we also see the ‘belt of tropical activity’ is once again girdling the Earth just north of the equator. This is shown in the satellite image below:

Other satellite imagery on 30 July 2011 shows equally active basins throughout the northern tropics, such as in the eastern and western Pacific and in the northern Indian Ocean, as seen below:
