Hurricane Dorian Live Thread II

NHC/NOAA ^ | 2 September 2019 | NHC/NOAA

[NautiNurse]

Catestrophic Hurricane Dorian was assigned Category 5 status by the NHC Sunday, September 1 at 0800. Since then Hurricane Dorian reached maximum sustained winds of 185 MPH, with gusts exceeding 220 MPH, and storm surge 18-23 feet above normal tide levels as it made landfall across Great Abaco Island in the Bahamas. Dorian became the strongest hurricane in modern records for the Northwestern Bahamas.

Dorian has wrought extreme wind and flood damage to Abacos and Grand Bahama Island as it crawled slowly across the Northern Bahamas.

All interests along the Atlantic coast should continue monitoring conditions and forecasts as powerful Hurricane Dorian moves very close to the US coastline. Evacuation orders have been issued for many Atlantic coastal communities in the Southeast US. Evacuations include multiple hospitals and nursing homes along the coast with anticipated dangerous storm surge and battering waves.

Wind speed is expected to weaken and fluctuate in the coming days as the storm moves northward.

NN,

Thank you for all that you do for us. It is greatly appreciated.

[MustKnowHistory]

Thanks for these wonderful threads!

Thank you for what you are doing here.

I’m in Columbia, SC myself and am keeping an eye on this storm. Any high winds and heavy rains are big deals to me.

I’m just curious... someone posted a link showing the wind speed at various altitudes. Such as 10 meters, 100 meters, 250 meters, 1000 meters etc., and on up to higher altitudes.

It appeared to me that the wind velocity was higher at high altitudes, but not so high at ground level.

Does anybody know... when they say a wind speed of 150 mph, does that mean at ground level, or at high altitude?

[crusty old prospector]

There is friction close to the ground. Especially if there is topography and trees.

I don’t trust those guys on TWC. They ALL seem to share the same opinion and all they can have right now is an opinion.

[Lurkina.n.Learnin]

Bump for later

[sport]

I would presume that the speeds shown or announced were at ground level. But that means nothing here or there, just my take on it.

Yeah, they are hard to take, especially when Cantore and the globull warming babe go into one of their weather gloom diatribes.

Is it unusual for a storm to move this slowly?

[campaignPete R-CT]

Stay safe.

SC coast being evacuated

[Vaden]

So glad to see it finally weakening a little. The 11:00AM report shows it at 155 MPH. It’s important to remember that it is still about as strong as Michael was last year. The satellite images show the eyewall is no longer that picture perfect circle so I am hoping it will go into an eyewall replacement cycle and weaken faster.

Not at all. Storms slow down for a turn and when they altogether lose steering currents. The storms known for their devastating flooding were pokey or stalled over an area for an extended period.
