Special Tropical Disturbance Statement 3

Nothing new in regards to the tropical wave located between Puerto Rico and the Dominican Republic. The wave has dumped tremendous amounts of rain over Puerto Rico causing rivers to rise and bridges to collapse. Luckily, the tropical wave should not affect Haiti because they really can not take anymore rain. Below is an excerpt of the Special Tropical Disturbance Statement issued by the NHC:   

AN AIR FORCE RECONNAISSANCE MISSION FLOWN THIS AFTERNOON INTO THE BROAD LOW PRESSURE AREA OVER HISPANIOLA INDICATES THIS SYSTEM HAS NOT BECOME ANY BETTER ORGANIZED...AND STILL LACKS A WELL-DEFINED LOW-LEVEL CIRCULATION CENTER. SINCE UPPER-LEVEL WINDS REMAIN SOMEWHAT FAVORABLE FOR DEVELOPMENT...THIS SYSTEM STILL HAS THE POTENTIAL TO BECOME A TROPICAL DEPRESSION DURING THE NEXT DAY OR TWO AS IT MOVES SLOWLY NORTHWESTWARD OR NORTHWARD AND AWAY FROM HISPANIOLA. REGARDLESS OF WHETHER OR NOT THIS SYSTEM BECOMES A TROPICAL DEPRESSION...IT WILL CONTINUE TO PRODUCE VERY HEAVY RAINFALL OVER PUERTO RICO...THE U.S. AND BRITISH VIRGIN ISLANDS...THE DOMINICAN REPUBLIC...AND HAITI THROUGH WEDNESDAY. THESE RAINS COULD CAUSE LIFE-THREATENING FLASH FLOODS AND MUD SLIDES

There is a low pressure system near North Carolina that is attempting to form into a tropical or subtropical cyclone. A subtropical cyclone is a system that has no tropical characteristics associated with it, but has everything else a tropical cyclone would have. This system should affect the middle half of the east coast as stated below. Read the official statement below:

SATELLITE IMAGES INDICATE THAT THE LOW PRESSURE SYSTEM CENTERED ABOUT 250 MILES...400 KM...SOUTHEAST OF WILMINGTON NORTH CAROLINA IS ACQUIRING SOME TROPICAL CHARACTERISTICS. THIS SYSTEM COULD BECOME A TROPICAL OR SUBTROPICAL CYCLONE LATER TODAY OR TONIGHT AS IT MOVES WESTWARD OR WEST-NORTHWESTWARD. THE LOW IS ACCOMPANIED BY WINDS OF UP TO 65 MPH...100 KM/HR...TO THE NORTH AND NORTHWEST OF THE CENTER. REGARDLESS OF DEVELOPMENT THIS SYSTEM WILL BRING STRONG WINDS...COASTAL FLOODING...HIGH SURF...AND DANGEROUS RIP CURRENTS TO PORTIONS OF THE U.S. EAST COAST DURING THE NEXT COUPLE OF DAYS. SEE STATEMENTS FROM LOCAL NATIONAL WEATHER SERVICE FORECAST OFFICES FOR ADDITIONAL INFORMATION AND WARNINGS. AN AIR FORCE HURRICANE HUNTER AIRCRAFT IS SCHEDULED TO INVESTIGATE THE SYSTEM THIS AFTERNOON.

A lot of talk has been generated from these two systems because there is a good possibility that they will be close enough to each other to create the Fujiwhara Effect. That occurs when two systems, tropical storm or stronger, approach within 900 miles of each other. At that point, their centers will begin to orbit at a point between the two centers. Although rare, eventually these systems will spiral into the center point and merge. The stronger storm absorbs the weaker one. To understand better how the Fujiwhara Effect works, imagine two skaters that are spinning and they join hands.

 

Everything else in the tropics is quiet. Stay tuned to Enrique6 News for another update from our Hurricane Center.
