The vigorous broad tropical low pressure in the northern Gulf of Mexico…designated potential tropical cyclone three…is making landfall on the Louisiana coast…it is not expected at this point to be upgraded to a named storm but currently is still producing tropical storm force conditions in its eastern rain bands:
**Parts of coastal southeastern Louisiana…coastal Alabama…and coastal Mississippi have seen gusty winds over the last several hours (as seen by the Boothville, LA; Gulfport, MS; and Mobile, AL National Weather Service station data). Isolated tree damage…power outages…etc…are possible.
**Based on the latest doppler radar…the heaviest rainfall with flash flooding potential had ended for SE Louisiana…and will not be reaching eastern Arkansas…due to the more east track this system has taken and also due to upper-level winds pushing the heaviest weather of this system down east. Watching for the spreading of heavy rain from now and thru this weekend across Mississippi… Alabama… Georgia… northwest Florida… Tennessee… Kentucky… West Virginia… Virginia…the Carolinas… Maryland… and Delaware. Should you encounter a flooded road…do not drive into the water or your vehicle could become stuck and you could drown.
**The remnants of this system have potential to redevelop over land and then along or just offshore the US east coast Sunday thru Tuesday either by tropical mechanisms… non-tropical mechanisms… or both. As such… gusty winds with isolated damage potential could occurr over eastern Tennessee… northwest Georgia… the Carolinas… Virginia… Maryland… and/or Delaware on Sunday and into Monday. Quickly passing coastal sea swells and rip currents as well as offshore choppy seas are a possibility Monday through Wednesday from the Carolinas through New England on the US Atlantic coast…and the Nova Scotia coast. The potentially strengthening remains of this system could impact Nova Scotia directly with wind on Wednesday depending on the exact track.
