Maybe it was close to hurricane status earlier?

[NDG]

Recon found hurricane force winds at flight level.

[CrazyC83]

Recon found hurricane force winds at flight level.

That is adjusted by multiplying by *.80, so it supports a 55 kt intensity. Based on convective trends, I think it was 60 kt earlier.

Had to pull the clouds off, too hard to resolve...

here link to news here about torando in farm area of broward this was wild south fl weather early in morning i count weather radio going on like 4 time after 3am in morning here link http://miami.cbslocal.com/2013/06/06/wi ... alm-beach/ one guy from wfor is storm chaser in early days so supprise to do one south fl

Maybe it was close to hurricane status earlier?

I bet they would had found some hurricane force winds at ground with earlier convection wrapping around her LLC.

don't think it was a hurricane earlier. This is now intensifying through baroclinic forcing. It will likely strike at peak intensity.

However, why were there not 6 hourly fixes planned for this?

It will strike at peak intensity. What intensity will that amount to do you think?

That's one ugly looking storm haha. Be safe everyone!

Recon supports a 55 kt intensity right now.
