The First Half is coming to an end!

Speaking in sporting terms relative to the 2013 Atlantic Hurricane Season it could be said that it is a couple of minutes before half time, in other words the first half of the hurricane season that matters the most to us here in Florida, or to those who live along the Gulf or Atlantic coastal USA states, is almost over. So far so good, unless you consider that the historical record shows that the most active part of the Atlantic Hurricane Season also starts about now and normally last through mid-October. So, do not broadcast the ‘all clear’ yet, rather the prudent thing to do is to pay attention, be prepared and practice mitigation!

What is happening tropical cyclone-wise in the Atlantic basin on this Tuesday 13 of August 2013?  There is a strong tropical wave in the Central Caribbean just southwest of Jamaica that is generating quite a bit of rain throughout the region at it moves  generally westward toward the Yucatan Peninsula, which is showing some potential for cyclonic development in the next day or so as it moves into a favorable low wind-shear warm surface water ocean-atmospheric environment. All interest in the Caribbean sub-basin will do well to pay attention to this system and monitor its progress in the next 24-48 hours.

Farther to the east over hurricane alley and even farther, over the eastern Atlantic near the Cape Verde Islands there are a couple of tropical waves that may warrant monitoring over the next few days as they continue to move toward the Lesser Antilles and the Caribbean. related to this on this day we also observe a train of tropical waves moving westward over Equatorial Africa adding fuel for potential cyclonic activity as they emerge over the warm waters of the eastern Atlantic.

Elsewhere in the world the eastern Pacific basin has continued to maintain a high level of activity including even today, when we see a few tropical waves or cells of disturbed weather, including two that may warrant further monitoring and investigation, which are following pretty much along the same path recently traveled by tropical Storm Flossie and Hurricane Gil so all interests in the state of Hawaii will need to keep an eye on these systems now extending from the eastern Pacific toward the vicinity of our 50th state.

Today also, there is major Typhoon UTOR over the South China Sea and the extreme western Pacific heading for landfall somewhere between Hong Kong and Hanoi in the next few hours after having hit the Philippines as a category 3 tropical cyclone. Satellite imagery from 12 August, as the storm approached landfall in the Philippines, and from today when the typhoon is traversing the South China Sea, show regions of intense rain and thunderstorms impacting a rather large region.

Following in UTOR’s footsteps over the far northwestern Pacific Ocean, moving toward the Philippines Sea there are a couple of cells of disturbed weather that are showing some potential for further development in the next couple of days. Residents of the Philippines and other countries in that region, which has seen a steady flow of rather wet disturbed weather cells over the past ninety days or so, must remain vigilant.

This is the ‘pre half-time report’, let us be ready for whatever the second half of the 2013 Atlantic Hurricane Season may bring us. Pay attention! Be prepared!! MITIGATE!!!

GOING OUT WITH A BANG?

In the course of just over one week since SANDY generated from a tropical depression in the Caribbean, became a tropical storm and reached hurricane strength as it hit Jamaica and then Cuba, also affecting Haiti and the Dominican Republic. It then continued over the Bahamas, creating concerns among residents of Florida as all of the peninsula’s east coast found itself within the “cone of uncertainty used by The National Hurricane Center to surround the predicted track of a tropical cyclone.

In moving over The Bahamas hurricane SANDY began following what could best be  described as a zigzagging track, first aiming toward the northwest paralleling the coast of Florida, but then turned north and later on toward the northeast paralleling the coast of Georgia and South Carolina, only to start describing another turn to the north and then the northwest aiming toward the mid-Atlantic and northeastern coastline of the USA.

In the process of meandering over the western Atlantic following the USA coastline Hurricane SANDY also began growing in size until it has become quite a large storm menacing hundreds of miles of USA coastline from North Carolina to Maine. It appears storm surge will be the main hazard as this behemoth of a tropical cyclone interacts with the numerous bays, sounds, inlets and other topography along the coastal region, which generate a funneling effect on the rushing waters contributing to storm surge and waves of enormous height. However, inland flooding and strong winds will also add to the impact, and could cause sever damage and human suffering.

With SANDY being the 19th named storm of the 2012 Atlantic Hurricane Season are we already seeing the last of the season? Is this the 2012 Atlantic Hurricane Season going out with a bang, or is there more fuel left in the tropics so that we may still see additional cyclonic activity in days and weeks to come? After all the “official” season, as if Mother Nature really pays attention to this,  still has more than four weeks left to go.

Regarding the possibility of more fuel left in the tropics to support additional tropical cyclone activity in the Atlantic, there are currently two tropical waves moving along hurricane alley that may warrant paying attention to over coming days, for any signs of potential further development.

Elsewhere in the world, there is tropical cyclone activity in the South China Sea at the northwestern extreme of the Pacific Ocean, where Typhoon Son-Tinh is making landfall over Viet Nam over the Gulf of Tonkin near Haiphong and Hanoi. Also in the Pacific there is a good sized tropical wave half way between Hawaii and the Philippines while closer to our region, over the Eastern Pacific,  there is a large elongated cell of disturbed weather and low pressure extending from just off-shore Central America to about 1,000 kilometers SSW of Acapulco, Mexico, which may show some potential for cyclonic development.

There is also plenty of stormy weather over the northern Indian Ocean where we see a large cell of low pressure, showing some signs of potential cyclonic activity, over the southern end of the Bay of Bengal, off the coast of India near Madras and the nation of Sri Lanka, which may warrant close monitoring over the next couple of days. On the other side of the subcontinent, off the west coast of India over the Arabian Sea there are some areas of disturbed weather that may warrant monitoring.

The southern hemisphere is relatively quiet at this time, except for a couple of areas near New Zealand and over Australia, although there are large areas of disturbed weather and strong winds near the extreme southern latitudes.

How damaging will the impact of Hurricane SANDY be over the USA? Is SANDY the last activity of the 2012 Atlantic Hurricane Season? How much more cyclonic activity will there be in the northern hemisphere? When will the southern hemisphere start to see more tropical cyclones? How will 2012 rate in terms of total tropical cyclone activity worldwide compared to previous years? Yes, there are a number of questions that we would like to have answered, but we will have to wait until after the end of the year for some of those answers.
