Folks in Houston/Beaumont, TX remember the flooding last year from Hurricane Maria. However, that was about 50 inches of rain.

Unfortunately, places like Pennsylvania which recently have flooded may see rain from this system.

New Bern, NC is in the Bullseye of the heavy rain - currently.

This map can change over the next few days before Florence makes landfall.

For Texas last year, the NWs did properly forecast the rainfall potential, but folks did not believe the prediction of about 50 inches of rain for Houston.

Hurricane Harvey caused the situation by being almost in one spot for so long last year...

The number of inches of rain is over an extended period of rain - Days 1 to 7...

Too many hurricanes last year:

The following refers to Hurricane Maria:

It should refer to Hurricane Harvey last year:

Unless it changes it will be bad. New Bern is at the convergence of the Neuse and Trent Rivers. The downtown area floods anyway. This much rain and storm surge will be catastrophic.

Get out now.

I would already be gone.

Don’t mess around with a strong hurricane.

Maybe it will be nothing, maybe it will be the end of the world.

If someone had a trip planned to, say, Virginia... to arrive in Richmond Saturday afternoon and be in the state until Friday, 9/21.... What is the best advice? Wait to decide? Cancel now? Go and risk it?

I don’t have a crystal ball but if the current track and intensity holds and it was me I wouldn’t want to be coming into Richmond on Saturday.

I did a google maps on NEW BERN, NC. There was not much there - except they did have a National Guard center.

They might want to move the High Water rescue trucks to higher ground (if there is any around there...

The satellite seemed to show High Water Trucks at the National Guard Center...

If you are flying into Richmond, that Saturday flight may be cancelled or severely delayed.

If you are driving, make sure you got a good set of tires and wipers; hopefully on a low profile vehicle...

You don’t want to be anywhere near one of these things. And afterwards it will take a few weeks to resemble normalcy.

I believe the storm has the potential for having over 10 inches of rain there and the potential for 60 mph to almost 90 mph winds - according to NHC maps.

My rule would be:

Necessary business trip - go.

Unnecessary business trip - postpone.

A trip for pleasure - cancel.

Map of potential wind forecast:

They say Florence is going to stall as it makes landfall. The winds will die down pretty quick but it's going to rain and rain. Flooding will likely cause more damage than winds, even 100 miles inland with fresh water flooding.

Hurricane Florence Discussion Number 48 NWS National Hurricane Center Miami FL AL062018 500 AM AST Tue Sep 11 2018

Recent satellite imagery shows that the eye of Florence has become cloud filled and an earlier 0441 UTC microwave overpass revealed a double eyewall structure. These observations suggest that an eyewall replacement cycle is likely underway. Subjective and objective Dvorak current intensity numbers have not changed so the initial intensity will remain 120 kt for this advisory. An Air Force Reserve Hurricane Hunter mission is en route to the storm and should provide a better assessment of Florence's structure and intensity this morning. NOAA buoy 41049 located about 80 nmi north of the eye, has reported tropical-storm-force winds during the last several hours and seas as high as 23 ft.

Florence's upper-level environment is predicted to remain quite favorable while the storm traverses sea surface temperatures of around 29C over the next 48 hours. Additional strengthening is forecast during this time, but some fluctuations in intensity are likely due to eyewall replacement cycles. The updated NHC intensity forecast once again calls for additional intensification and brings Florence to near category 5 strength within the next 24 to 36 hours. After 48 hours, a slight increase in southwesterly shear could result in some weakening, but Florence is expected to remain an extremely dangerous hurricane when it approaches the U.S. coastline.

Florence has accelerated as anticipated and is now moving west-northwestward or 290 degrees at 13 kt. The track forecast reasoning has not changed much. A mid-level ridge to the northeast of Bermuda is expected steer Florence quickly west-northwestward to northwestward toward the southeast United States coast over the next 2 to 3 days. By 72 hours, a high pressure ridge building over the Upper-Midwest and Great Lakes regions is forecast to cause a significant reduction in Florence's forward speed and the hurricane is predicted to meander over the eastern portions of North or South Carolina at days 4 and 5. The ECMWF has trended slower this cycle at days 4 and 5, and as a result the NHC forecast shows slightly less motion at those time periods. The spread in the guidance increases by 72 hours, with the GFS and its ensemble mean along the right side of the guidance, while the ECMWF remains along the left edge. It should be noted that there are still a number of ECMWF members that are even farther left. The NHC track forecast has been nudged to the left and is close to the TVCN consensus aid. Given the amount of uncertainty by day 3, it is important not to focus on the exact forecast track as average NHC errors at days 3, 4, and 5 are about 100, 140 and 180 n mi, respectively, and dangerous hazards will extend well away from the center. Storm Surge and Hurricane watches have been issued for a portion of the coast of South and North Carolina. Additional watches may be required later today.

Key Messages:

1. A life-threatening storm surge is likely along portions of the coastlines of South Carolina, North Carolina, and Virginia, and a Storm Surge Watch has been issued for a portion of this area. All interests from South Carolina into the mid-Atlantic region should ensure they have their hurricane plan in place and follow any advice given by local officials.

2. Life-threatening freshwater flooding is likely from a prolonged and exceptionally heavy rainfall event, which may extend inland over the Carolinas and Mid Atlantic for hundreds of miles as Florence is expected to slow down as it approaches the coast and moves inland.

3. Damaging hurricane-force winds are likely along portions of the coasts of South Carolina and North Carolina, and a Hurricane Watch has been issued for a part of this area. Damaging winds could also spread well inland into portions of the Carolinas and Virginia.

4. Large swells affecting Bermuda and portions of the U.S. East Coast will continue this week, resulting in life-threatening surf and rip currents.

No such thing as a “necessary” business trip into a hurricane zone. If that’s the decision you’re faced with, your boss is a complete moron.

If I were in your situation, I’d decide it’s a nice time to visit some place like KY or WV. Keep in mind that nearby area to the storm that don’t get hit will have disruptions.

Harvey was a triple storm. High winds and surf hit the mid coast area, Houston got over 30 inches of rain, and Beaumont/Port Arthur got around 65 inches of rain.

In 2001, tropical storm Allison dumped 32 inches of rain in the Houston area. It was “just” a tropical storm.

Point is, any of these storms can be devastating.

If you have a hotel room reserved, give it up for potential evacuees.
