A complex weather system near the Bahamas is forecast to move westward and it will bring gusty winds and locally heavy rain to parts of the Bahamas and South Florida during the weekend.\u00a0 The circulation is strongest in the middle and upper troposphere.\u00a0 An upper level low is centered near the Bahamas.\u00a0 Showers and thunderstorms are occurring north and east of the upper low.\u00a0 There is not a distinct center of circulation in the lower troposphere or at the surface.\u00a0 There is a small upper level ridge to the east of the upper low and the ridge is producing some upper level divergence which is pumping mass away to the east of the system.<\/p>\n
The system will move through an environment that is only marginally favorable for the development of a tropical cyclone.\u00a0 It will move over water where the Sea Surface Temperature is near 26\u00b0C.\u00a0 So, there is potentially enough energy in the upper ocean to support the development of a minimal tropical cyclone.\u00a0 The upper low and the ridge to the east are southerly winds near the Bahamas and westerly winds southeast of the Bahamas.\u00a0 Those winds are causing strong vertical wind shear.\u00a0 The winds are weaker near the center of the upper low, but there are no thunderstorms in that region at the current time.\u00a0 If a surface low were to develop under the center of the upper low, then there would be the possibility of some slow development.\u00a0 A second, possible scenario is that a subtropical cyclone develops north and east of the upper low where the showers and thunderstorms are forming.<\/p>\n
The National Hurricane Center (NHC) issued a special Tropical Weather Outlook on this system at 10:45 a.m. EDT on Friday.\u00a0 NHC indicated that “no significant development” is expected and it gives a 0% probability of the formation of a tropical cyclone.<\/p>\n
The upper level low is forecast to move south-southwest over the northwestern Caribbean Sea during the next 72 hours.\u00a0 The surface and lower parts of the system are forecast to move across the Bahamas toward South Florida during the weekend.\u00a0 Since the showers and thunderstorms are occurring north and east of the upper low, this could bring gusty winds and locally heavy rain to parts of the Bahamas and South Florida during the weekend.\u00a0 Some of the humid air on the northeastern periphery of the system could be pulled toward the Carolinas ahead of an approaching cold front.\u00a0 The moist air could enhance rainfall in eastern South Carolina and eastern North Carolina when the cold front moves through those places and lifts the air.<\/p>\n","protected":false},"excerpt":{"rendered":"
