It's a measurement taken over water, friction reduces the higher sustained winds as it comes on land. 1 1 Link to comment Share on other sites More sharing options...
WxWatcher007 Posted 1 hour ago Author Share Posted 1 hour ago Just now, Interstate said: Wrong... when they say 105 MPH per hour... that means sustained... and there is no way any place over land will see those kinds of winds Yeah that’s my point. Those offshore sustained winds rarely get measured onshore. Idk why people here think those NHC operational winds will tear through the landfall zone. The gusts imo tell the story. They’re legit. 2 1 Link to comment Share on other sites More sharing options...
Interstate Posted 1 hour ago Share Posted 1 hour ago 10 minutes ago, WxWatcher007 said: Max winds at 105 looks about right given onshore obs and gusts. Y’all do this every hurricane lol. We also know that the NHC never drops the wind speeds like the should on a hurricane that has moved over land... they only decrease it like 5 or 10 MPH at each advisory.

WEATHER53 Posted 1 hour ago Share Posted 1 hour ago 4 hours ago, vortex95 said: The thing is the models shows the thing getting ripped apart clearly, the primary HU models as well (HAFS) Why wouldn't you think that w/ the shear increasing to 40 kt and that much dry air present? There have been other cases like Isaias,, but also cases where unexpected rapid weakening occurs as well (Katrina and LIli are prime examples). So you can't fault ppl for driving the point home. We have a strong baroclinic situation here, so one wouldn't just ignore than. I would not say rapid intensification not long before landfall used to be definite rarity. That is recency bias largely. Since 1995, we have been in an active phase of the AMO for favorable Atlantic TC activity. Also, we are much better in determining absolute intensity now, esp. for the stronger HUs b/c of things like the GPS dropsonde, which did not come into use until 1998, and the SFMR, which did not exist on recons until 2004. This advancement in tech has allowed us to diagnose *much* better extreme winds that we could not directly measure before. Prior, it was largely just FL winds at 700 mb, but that serves only as a proxy and does not work all the time. So in recent decades we are seeing things we never could detect before, but were always there. Also, and this is a biggie, through the 1960s, if a hurricane was thought be 100 kt or stronger, many recons wouyld not penetrate the eyewall and get into the eye for direct measurements. They would fly only as close enough to get a solid radar scan of the eye, and then turn away. So many HUs were underestimated by 1 or even 2 categories at times in the first decades of the recon era! Because Things don’t always work like a model showing 40k shear ripping things apart . So I look at what’s been happening last 25 year that’s different than 25 before that . These storms intensify or hold their own moving onshore or onto land now. I just don’t remember that from 50’s into 90’s You mentioned how it can align some with the shear direction and does not weaken as much . .
