Super Typhoon Mangkhut (equivalent to a Category 5) is about to make landfall in Luzon with 165 mph winds, after peaking with 180 mph.

It intensified to 175 mph just prior to making landfall at about 1810 UTC (2:10 pm EDT). This storm is a monster. (I founded the Pacific Typhoon Season group on Facebook, btw. :P)

Who says?  Weather dot com reports current winds of NNE 57 mph at Wilmington.

Says satellite radar from this morning, Wrightsville Beach NC is just south of Wilmington. Via NHC Twitter:

NEW: #Hurricane #Florence has made landfall near Wrightsville Beach, North Carolina at 7:15 AM EDT (1115 UTC) with estimated maximum winds of 90 mph (150 km/h), and a minimum central pressure estimate of 958 mb (28.29").  http://hurricanes.gov

If you mean the Weather Channel, yeah I'd hype up the storm for ratings as well cause that's what TWC turned into. NWS and NHC tuned the track and strength as needed when new data came in and got the message out to get people out of the way of danger. They gave North Carolina a week's worth of lead time before landfall to prepare and evacuate. I say that's a job well done for the NHC and NWS local offices

You creatively snipped the list of Wilmington local data that I compiled in realtime.  They reported 72 mph which is a lot lower than 90 mph and is not even hurricane strength.  Only 2 hours did it even get above the 60s.

Sorry, but scaring the whole middle Atlantic area with Fake Forecasts of a high Cat 4 hitting N.C. is not a responsible way to alert the population to take measures.  It is very irresponsible and is driven by scare politicization.  I live 120 miles from the Atlantic but I know how nasty things can get even here from when a storm comes ashore in N.C., and I don't need or appreciate this tommyrot.  The National Weather Service actually had a forecast several days before landfall that Richmond on Thursday "hurricane conditions possible", that would be 74+ mph sustained winds.

That's why it's called the Cone of Uncertainty and that they always put in the message "Monitor latest forecasts for track and strength changes". They make the cone that big based on model plots and the size of the hurricane at the time of the advisory to show how large of an area it could affect. So yes, early on it had a possible landfall between Richmond and the SC/GA border. But as the week went on, it shrunk the cone as accuracy improved. Would you rather give people only a couple days heads up to evacuate or at least a week to least have people take notice that there could be a landfall and begin to make a plan of action and monitor the latest track? That's not fear mongering, that's just getting the message out. I believe VA was cleared out of the landfall cone by late Tuesday/early Wed and that many of the supplies gathered in case Florence went north got stockpiled and now will be used to help with the Carolinas

Luckily we live in a time where the technology has helped the accuracy of tracking hurricanes improve each year  :nod:

I wasn't discussing the size of the cone, I was discussing the intensity.  A storm that is barely Cat 1 will have vastly lower effects in wind damage and storm surge, as compared to a high Cat 4.  Given the extreme rarity of any Cat 4 storm making landfall in N.C., yes it was fear mongering, pure and simple, any way you slice it.

Key word there is "possible". For what it's worth, the NHC never forecasted any landfall above 140 mph. But that's irrelevant. What is relevant is the fact that our weather forecasting technology is not perfect. If you had actually read the forecast that far in advance, it likely said something to the effect of "It is too soon to know the exact impacts, but prepare for the worst" or "the intensity forecast is uncertain at this point". That's not a "fake forecast", that's responsible warning. ET21 is right on point here. Last year, Harvey made landfall in Texas as a Category 4, which wasn't expected to happen until it actually did. The NHC wants people to prepare for the worst -- which is proper. If this storm had changed direction and hit SC instead (which could easily have happened), wouldn't you want them to be prepared and evacuated if necessary? This storm had the potential to be worse than Hugo for South Carolina -- and anyone who remembers that isn't likely to want to go through it again.

Sure, there was some hype for this storm, but absolutely none of that comes from the NHC. Anything to that effect is from news outlets and tabloids looking for clicks and ratings, which is why I wouldn't trust them. I would trust the NHC and NWS over all other forecast outlets.

Also, I wouldn't tell a North Carolinian right now that this storm was overhyped. This storm has already broken the tropical cyclone rainfall record for North Carolina, and several rivers are experiencing catastrophic flood crests, some at record levels. Places have seen more than thirty inches of rain. Dams are failing because of the amount of water. I-40 and I-95 are both shut down, and Wilmington has essentially been cut off from the rest of the world. Nearly 20 people have died. This storm has been worse than Floyd or Matthew, and it might well go down as North Carolina's worst tropical cyclone ever. Oh, and Wilmington didn't get the maximum winds because the storm didn't directly hit Wilmington; it hit Wrightsville Beach.

Who cares what part of the government the NHC is in? If you ask me, just because it's part of the government doesn't make them any less reliable; in fact, it makes them more reliable, since the government isn't trying to get ratings and clicks like other private forecasting agencies. And insulting the NHC and local NWS offices by calling their forecasts "fake" is, IMO, incredibly rude to the forecasters down there who have spent tireless hours working to help the American people. They did the absolute best they could with what they had at the time, and I appreciate their work.

Nope. Florence was far worse than your average Category 1, because of the large size of the storm and wind field. That means more places experiencing hurricane force winds and rain, but more importantly, it means a larger storm surge. If Florence had been a high-end Category 4, it would almost certainly have been a smaller storm. The winds would have been more destructive near the point of landfall, but areas farther from that point would see much less impact. Remember Sandy? That was "only" a cat 1-equivalent hurricane at landfall, but look what it did.

It's worth noting that the Saffir-Simpson scale only measures winds, which isn't exactly the most helpful indicator of a storm's damage. Winds are not typically the cause of most of the damage; the vast majority of hurricane damage is due to flooding, whether it be storm surge or rainfall. Again, they were preparing people for the worst here. This was not fear mongering; the NHC forecasts were what they felt most confident in at the time.

Also, if you read the forecast discussions, you'll notice the NHC did not play up the forecast intensity of the storm at landfall, as the intensity part of the forecast was much less certain. They focused on the two highest-probability events: storm surge and inland flooding, both of which verified.

Other than two tornadoes coming within about a mile of my house, I'm fine. Apparently there were four confirmed tornadoes in Chesterfield County alone, including the particularly destructive one near Hull Street Road and Genito Road that killed one person and injured another (that tornado was probably the biggest/widest one I've ever seen around here).

I saw a video on one news site of the one that was in the process of destroying the warehouse at Speeks Drive near Hull Street Road, and it definitely was a tornado.   I just now looked at an article on the Richmond Slimes-Dispatch website, and it says that there were 19 tornado warnings issued yesterday but other than the one tornado they don't specifically mention another touching down, although supposedly other funnels were seen.  Reports of big trees down in some places, and up to 11,000 customers without electric power yesterday.  Bad thunderstorm activity, it happens from time to time, and I don't know that it had anything to do with TS Florence.  Very heavy rains in places, Stratford Hills area got at least 3.5 inches yesterday.  The drainage swale next to my lot is normally dry and at the peak it was a roaring brook.
