The Caribbean and Eastern East Pacific Flare-up on 5 June 2011!

On the fifth day of the 2011 Atlantic hurricane season the region of disturbed weather that has lingered for the past few weeks at the junction of Panama and South America appears to be expanding into the Caribbean and the eastern east Pacific. The GOES satellite image [courtesy of NASA] for the aviation industry taken on 5 June 2011, shown below, illustrates:

The solid yellow outlines on the image above identify the two areas of low pressure that have generated cells of disturbed weather, thunderstorms and heavy rain over the Caribbean and the eastern east Pacific. The Caribbean cell is moving northwest by north and is already causing heavy rains over Jamaica, Haiti, the Dominican Republic and portions of Cuba. Both these cells are being monitoredby the National Hurricane Center and NOAA’s Tropical Prediction Center for potential further development over the next 24-48 hours. Although the eastern east Pacific cell is  moving away from the continental landmass, the combination of both cells has generated some rain over the Yucatan peninsula, especially Quintana Roo state in Mexico, which have been under drought conditions for some time now. These rains are a welcome development in Quintana Roo where wild fires have affected several areas in the state. The potential for rain nay be as high as 51 mm over the next few hours, as it is illustrated by the regional map shown below:

In the mean time the area of low pressure and associated storm cell over the eastern east Pacific appears to be getting better organized as it flows over an area of rather warm surface water [30+ Celsius]. Other cells of disturbed weather off the coast  of Nicaragua, and further south near Panama and Colombia and over the northern regions of Colombia and Venezuela appear to be linking with large cells of disturbed weather moving westward over hurricane alley an it is shown on the satellite image below:

While the Caribbean and eastern east Pacific are flaring-up on 5 June 2011, the central Atlantic and especially the far eastern Atlantic are also being affected by large regions of disturbed weather, which are generating rain and thunderstorms. As was expected with the nearing advent of the summer solstice, the tropical wave assembly line over equatorial Africa has become quite active feeding pulse after pulse of tropical activity to hurricane alleyThese tropical waves have the potential for contributing to cyclogenesis [generation of tropical cyclones] as they ride along hurricane alley toward the Caribbean and the central Atlantic. Currently several tropical waves are moving westward along hurricane alley while others form a train of tropical pulses over equatorial Africa as shown on the satellite image below:

An overall picture of all of the conditions described above can be gained from the full-disk composite satellite image of Earth’s western hemisphere on 5 June 2011, which follows:
