SOUTH FLORIDA WEATHER UPDATE:
South Florida is under the influence of a strong ridge over the region. This has suppressed convection over most to all of the region today aside from the far western coast. Conditions should stay this way so as long as mid-level subsidence stays in place. The NWS expects a back door cold front to move into the region bringing drier air and lesser chances for precipitation. Nevertheless, thunderstorms could form over the interior areas due to sea breeze interactions.

WX UPDATE
SOUTH FLORIDA WEATHER UPDATE:
Heavy rain bands continue to move across South Florida as Tropical Storm Isaac swiftly makes its way across South Florida. Per NWS Miami, a wind gust of 64 MPH was recorded today at Port Everglades in Broward County. Sustained winds of 30-40 MPH are occurring in Miami-Dade County with locally higher gusts. The wind field is expected to die down in wake of Isaac tomorrow. However, the National Weather Service expects an area of low pressure to settle across the region. That combined with plenty of moisture from Isaac will lead to scattered thunderstorm formation across South Florida Tuesday and Wednesday.

SOUTH FLORIDA WEATHER UPDATE
SOUTH FLORIDA FORECAST 8/25/12:
Scattered thunderstorms can be expected today along with strong winds in any cell that develops. Expect very heavy rainfall along with localized street flooding that could be severe. Temperatures will be near 90 with heat indexes high. Winds will start to increase tomorrow as Isaac approaches. Also, tornadoes are possible over all of South Florida due to increased shear and low level wind profiles.
NOTE: Potential hazards have increased so be sure to check out the "NWS MIAMI" link on the right hand side of the page for more info. Also, check out the weather briefing.
UPDATE:
The latest NHC update on Tropical Storm Isaac has stated that Isaac has weakened some. Its minimum central pressure now stands at 998 mb w/maximum sustained winds at 60 MPH. Some strengthening is expected as Isaac emerges between Haiti and Cuba which has yielded a Hurricane Warning for all of the Florida Keys, Mainland Monroe, Far Southern Miami-Dade Counties. Tropical storm force winds extend out 230 miles from the center. Keep in mind that if you live on the NE portion of the center of circulation, you are in the worst part of the storm. Forward wind speed, circulation, and thunderstorm outflow all enhances wind fields. Whether or not Isaac forms into a hurricane depends on how much Isaac interacts with topography and how long it stays over water. None the less, expect hurricane force winds at your location.

South Florida Weather Analysis
SOUTH FLORIDA WEATHER UPDATE 8/24/12:
The forecast track for Tropical Storm Isaac has now changed and the system is no longer expected to become a hurricane near South Florida. However, those living in Louisiana and surrounding states should keep a close watch on the TS Isaac. That being said, South Florida is still not in the clear. Tropical storm force winds are still a possibility. In addition, any thunderstorms associated with squalls or the system itself can become severe and produce tornadoes. Therefore, a Tornado Watch could be issued by the National Weather Service if they deem the amount of shear to be sufficient for tornadogenesis.
FORECAST AND DISCUSSION:
Seasonal isolated to scattered thunderstorm development is possible over the region. Any thunderstorms can produce strong winds today. Temperatures will hover around 91 degrees Farenheit and lows will be in the upper 70s to lower 80s due to increased moisture and upper level cloud cover. For tomorrow, scattered storms are possible with highs around 91 as well.
