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:
The month of September 2010 is not over yet and it is already one for the record books in terms of tropical cyclone activity. We have seen plenty of activity throughout the larger basin, in the tropical North Atlantic, in the Caribbean and in the Gulf. Tropical cyclone activity this September has offered a wide variety of storms, from major hurricanes, to a hurricane that made it all the way to Greenland, to a tropical storm that actually spawned its own “clone” (Matthew), to storms that decayed and almost dissipated only to be reactivated again (Julia, Lisa).
As this post is being written “Matthew the Sequel” has become tropical depression #16 and it is moving north-by northeast toward South Florida and coastal regions beyond, in the Carolinas and up the eastern seaboard.
Looking east we see that ‘Hurricane Alley’ is already populated by a few tropical waves, some of which are looking rather threatening, and farter east over equatorial Africa and beyond over the Indian Ocean, numerous tropical waves of all shape and sizes continue marching westward to ride the ‘Tropical Wave Assembly Line” in Africa, which eventually may emerge over the eastern Atlantic and head in the general direction of the Caribbean, Gulf and USA Atlantic coastal regions.
The question is: have we hit the peak of the 2010 Atlantic Hurricane Season or are we in for another burst of activity in October similar to what we have seen in September? Only time will tell what will have transpired in what remains of the 2010 Atlantic Hurricane Season, but for now we must concentrate in monitoring all these waves as they appear over the horizon, while being prepared. As we have said throughout this season, Pay Attention! Be prepared!! MITIGATE!!
