Tropical TS Danny

Not bad for June. I wouldn't be surprised if they call it Danny at 5

Look at the NHC giving a shout out to Weatherflow lol @SD

...DEPRESSION STRENGTHENS TO A TROPICAL STORM...

Doppler radar data from Charleston, South Carolina, along with
preliminary data from an Air Force Reserve reconnaissance aircraft,
indicate that the depression has strengthened and is now Tropical
Storm Danny. The maximum sustained winds are estimated to be 40 mph
(65 km/h) with higher gusts.

A Weatherflow station at Folly Beach, South Carolina, recently
reported a wind gust of 41 mph (66 km/h).
 
Per radar and trends, we look to get the heaviest rainfall from a couple of bands on the west/SW side of Danny starting shortly and going for a couple of hours on and off. I wouldn't want to be driving then as tropical bands like this are often very heavy in spots. It looks to be coming at a bad time, drive home time. So far, only occasional very light rain has fallen with light winds.
 
.TROPICAL STORM DANNY STRENGTHENS SOME MORE AS IT NEARS THE SOUTH CAROLINA COAST.

Tropical Storm Danny Discussion Number 2
NWS National Hurricane Center Miami FL AL042021
500 PM EDT Mon Jun 28 2021

Deep convection has exploded this afternoon over the center of what
is now Tropical Storm Danny. Reconnaissance aircraft measured 49 kt
winds at the 850-mb fight-level, which equals roughly a 39-kt
surface wind. In addition, Doppler velocity data from the Charleston
radar measured average velocities of 49 kt at 6000-7000 ft, which
also equate to about 40-kt surface winds. A reconnaissance aircraft
dropsonde also measured a central pressure of 1009 mb. Based on
these data, the advisory intensity has been increased to 40 kt.

The initial motion estimate is 290/14 kt. Tiny Danny is forecast to
maintain a west-northwestward motion for the next day or so, with
landfall expected along the southern coast of South Carolina likely
occurring by 0000 UTC this evening. The small tropical cyclone
should continue to move inland across southern South Carolina and
eastern Georgia tonight and early Tuesday, with dissipation expected
over the mountains of northern Georgia by Tuesday night or early
Wednesday. The new NHC track forecast is a little to the left of
the previous advisory track, and lies close to the consensus track
models HCCA, TVCA, and GFEX.

No additional strengthening is anticipated before Danny makes
landfall. Rapid weakening should commence shortly after landfall,
with Danny likely becoming a remnant low by Tuesday morning.
The official intensity forecast follows a blend for the Decay-SHIPS
statistical model for inland tropical cyclones, and the intensity
consensus models IVCN and HCCA.

Key Messages:

1. Heavy rainfall is possible from coastal southern South Carolina
and Georgia, inland across the Piedmont of Georgia into northeast
Alabama. Isolated flooding is possible across urban areas of the
southern South Carolina and Georgia coasts.

2. Tropical-storm-force winds are expected across portions of
the South Carolina coast late this afternoon and tonight where a
Tropical Storm Warning is in effect.

3. Swells generated by Tropical Storm Danny are expected to affect
portions of the South Carolina coast through tonight. These swells
could cause life-threatening surf and rip currents.

Center aiming for Hilton Head or just north. Thunderstorms again here in SAV now with this 2nd band. Skies are dark. Winds are light.

This 2nd Danny band is a doozy here in SAV, Ga, with lots of CTG lightning (some very close hits..I hope I don't lose power) and heavy rains.

You may see several inches of rain under that band impressive on radar

Some crazy totals in your neck of the woods. Tbat lightning map was crazy for a while over Savannah
 
Mid level and LLC completely separated. Mid level rotation over East Central GA and a lingering low level swirl just NW of the Grays, SC (KCHS) at 10:55pm.
Doppler radar estimates up to 8inches in extreme Southern SC. Actual measured report of 5.42" in Effingham County GA with several reported destructive lightning strikes

I didn’t quite get several inches but I did get over an inch of rain (~1.5"). The most notable thing was the large amount of CTG lightning. I can’t recall a TS ever giving me that much. And the winds were mostly light. That makes sense as I was south of the LLC path, where winds were coming off the land. But that side was also much wetter.

It has been an unusually busy June here tropically with the gusty SW winds into the 40s from the outskirts of Claudette due to a pinched gradient and now the rain/CTG from Danny.

Didn’t expect this much rain from Danny. Lots of lightning as well. Very much like a MCS. Of course it occurs right after I scrape the driveway for the first time in three years.
