Roy Posted September 20, 2017 Share Posted September 20, 2017 Does anybody know what percentage of hurricanes weaken before landfall? Based on all the ERC talk, I expected to see this below cat 5 this morning, and we did. It "seems" like many hurricanes aren't intensifying or stable at landfall, or is this a false perception?

Roger Smith Posted September 20, 2017 Share Posted September 20, 2017 Just for the historical record in this thread, CNN reporters in San Juan and on east coast just north of landfall have taken cover inside and their videos of outside conditions appear consistent with cat-3 or cat-4 conditions ... they can't stand up to report from even sheltered spots outside. Meanwhile, eye approaching Arecibo on northwest coast, winds steadily increasing to NNE 62 knots gusting 85 knots at 0048z. Observing site on shoreline reports every 6 min, don't think we get to see next ten reports until 0148z transmission (but watching for them). No pressure report from this data buoy.

And this storm has a long history of completely stripping trees of their leaves. The sound in the video below is terrifying, it sounds like some huge monster exhaling through its teeth. Leaves stripped from the palm trees in that video. As a Midwesterner, I am not certain what wind speed they usually can withstand? Link to comment Share on other sites More sharing options...

It just bulldozed through almost dead center of the island. Damn With such a large city being blasted with such incredibly high wind velocities.

There was someone streaming from Trujillo Alto (SE of San Juan) and the winds had died down considerably. He claimed that they were probably under the eye (or perhaps they were under some gap).

Roger Smith Posted September 20, 2017 Share Posted September 20, 2017 On subject of "weakening" at landfall, in these cases where a strong hurricane approaches a hilly or mountainous region, we have to understand that the forward half of the circulation is being squeezed up so there would be some tendency for the surface elements of the eyewall region to be lifted up near the coast, net effect being a pressure rise and wind decrease at sea level but no doubt the cat-5 winds continued on to make an elevated landfall. When Patricia came inland there was evidence that pressures had risen 30-40 mbs in the six hours to landfall but winds at some elevation inland (northwest portion of eyewall) were still representative of lower eye central pressures, so really this discussion is somewhat moot, it depends on where you want to measure the winds -- but officially it is the conditions at the sea level landfall point. Those may not be known for a while but from the radar I suspect there may be patchy cat-5 damage evidence in the right front quarter of the eyewall. There will probably be widespread cat-5 type blowdown on ridges (and unfortunately the radar was located in such a spot). Link to comment Share on other sites More sharing options...

OSUmetstud Posted September 20, 2017 Share Posted September 20, 2017 I highly doubt san juan got cat 4 winds. 2 and 3 most likely. Elevated sections of eastern pr got 5 winds...but top end sea level winds die out very quickly out away from marine exposure in the ne eyewall.

wxeyeNH Posted September 20, 2017 Share Posted September 20, 2017 Watching the live news from San Juan. Winds are quite light. Are they in the eye area? I'm guessing the wind will come back ripping from the south? Link to comment Share on other sites More sharing options...

Roger Smith Posted September 20, 2017 Share Posted September 20, 2017 The Arecibo reports have updated for 1254z to 1318z and show a slight veering from NNE to NE, peak gust so far was at 1312z, 87 knots. Eye might come very close to this location soon. Link to comment Share on other sites More sharing options...

I agree that they probably didn't get sustained cat 5 winds there, but they probably gusted over 140MPH. Not sure if we'll ever know since it appears the equipment failed.

Fair enough. I dont know much about Tropical for sure. Would you like to explain to me what is wrong with the product when it is showing decreasing winds just before landfall?
