Danielle, Earl, Fiona, Kompasu, Lionrock, Namtheun etc

Two hurricanes, one of them a category 4, four tropical storms and at least six tropical waves are currently active in the northern tropics fulfilling our earlier assessment that the ‘tropics are hot’ and things are happening quite fast in the tropics. It would appear the 2010 Atlantic hurricane season has suddenly entered a whole higher level of activity after a slow start. Based on the systems currently active and what already appears in the horizon looking east from the Atlantic over equatorial Africa and the Indian ocean, it appears September is gearing up for a new level of tropical cyclone activity.

 A wider view shows additional tropical activity extending into the Indian Ocean as far back as Indonesia and over into the western Pacific where Typhoon KOMPASU is a category 2 tropical cyclone over the southwestern Ryukyu Islands of Japan, and tropical storms LIONROCK and NAMTHEUN are respectively south of the Ryukyu islands near Taiwan and southwest of Taiwan moving for landfall in mainland China. The composite Global Mosaic below shows a good part of such tropical cyclone activity over the Atlantic, Equatorial Africa and the Indian Ocean.

There is plenty of 'tropical fuel' to feed the 'tropical wave assembly line' over equatorial Africa and 'hurricane alley' in the tropical north Atlantic for at least the next two weeks.

The ‘belt’ of tropical weather circling the Earth just north of the equator appears to be firmly in place and fueled by enough activity to last for several days into September. It is interesting to note that two of the currently active systems, Danielle and Earl have both reached category 4 strength, Hurricane Earl went from category 1 to 4 in the span of one day, and Tropical Storm Fiona went from a tropical wave to tropical storm strength in one continuous spur of activity earlier today 30 August 2010. It is clear that conditions overland in tropical equatorial Africa and in the coupled ocean-atmosphere Atlantic environment continue to be favorable for tropical cyclone development and rapid strengthening of new storms.

Hurricane Danielle reaches Category 4!

On 27 August 2010 hurricane Danielle strengthened to category 4 over the open waters of the Atlantic as it continued to move toward the general region of Bermuda, At the same time Tropical Storm Earl continues to have maximum sustained winds of 45 mph and it is holding its generally due west course. Following behind is a large tropical wave to the southwest of the Cape Verde Islands, which continues to show signs of potential strengthening and tropical cyclone development at it is surrounded by favorable conditions. Not too fat behind several other tropical waves and areas of disturbed weather over equatorial Africa, and a far back as the Indian Ocean are all lined-up to get of the ‘assembly line’ and eventually ride ‘hurricane alley’ toward our neighborhood. It is clear all interest in the Caribbean and Gulf basisn, and in Florida and the rest of the USA Atlantic coastal region must be on the alert, paying constant attention to all of these potential threats being generated by Nature as we enter the historical peak of the Atlantic hurricane season. Pay attention! Be prepared!! MITIGATE!!!

Hurricane Danielle and Tropical Storm Earl are cleary visible, as well as several tropical waves marching from east to west toward the warm waters of hurricane aley in the Atlantic.
