not really very Tropical Storm Nestor (AL162019) SaturdayUpdate

As NHC notes in their forecast discussion this morning, Nestor really isn’t very tropical.  As I’ve been saying all along, structurally it’s more like a nor’easter.  While it is raining heavily across Florida this morning, there is very little convection or thunderstorm activity, mostly off the Atlantic shore over the Gulf Stream.  There do seem to be a lot of storm tracks with rotation in them.  Here is the 7:22am composite radar, long with a neat product from the “Multi-Radar Multi-Sensor” or MRMS system, low level rotation tracks …  those “streaks” in the map or the right are storm tracks where there is rotation, or potential tornadic activity.  That is probably the biggest threat from not-really-tropical Storm Nestor.Same map with the watch boundaries … as always, click to embiggen and see detail!

Expect tornado watches to expand north into Georgia and probably South Carolina later today, so keep your weather radio handy.  Finally, here is the forecast rain and surface pressure from the High Resolution Rapid Refresh model for 5pm this afternoon …

So again, bottom line, rain, gusty (but not dangerously high) winds, potential for tornadoes.  Try not to travel if you don’t have to, but if you are going to a football game or something take extra time, and bring a raincoat (the umbrella will just blow away 😛 ).
