How about we keep the recon reports in the recon reports thread?

What it should be looked like inside. The whole instrument is gone.

That's my fault sorry (re: Recon reports).

Wow, that shows the power of the winds. First NWS radar to be destroyed since the Miami radar in Andrew in 1992?

Sadly, they have to replace it with a brand new radar which is probably going to take a while. Let's hope no more hurricanes will come anywhere close to PR for the rest of season.

[PandaCitrus]

I think the Doppler Radar is on a 2000 foot mountain and was in the northern eyewall. It must have received some insane gusts.

[1900hurricane]

Here is the latest Coriolis pass. A giant outer eyewall is developing. Recon has shown a wind max with the feature. Maria probably will not exceed its current intensity for the rest of its existence.

Any chance of a legitimate link to the damage pictures?

Twitter is legitimate. Grumpy.

Ocracoke Island NC begins mandatory evac of visitors Monday morning.

[CrazyC83]

Based on all the data I have seen, I'd set the intensity at 75 kt.

NWS Reno's radar was severely damaged as well although not as thoroughly as San Juan's http://cimss.ssec.wisc.edu/goes/blog/archives/1581

Better. Other thing to note is that every single tree appears broken off.

That will never be cleaned up. We still have large numbers of damaged trees in the wooded areas from the ice storms in '09 and '10 and Ike's visit.

Any idea what’s going on with Maria? I mean shear looks low and SST’s have been plenty warm recently, but she looks horrendous tonight. Is it just that the inner core was so disrupted from Puerto Rico and the mountains there that she hasn’t recovered?

Looks largely a function of mid level shear to me. CIMSS upper level analysis shows shear undercutting the outflow level from the southwest. Sounding data from the Bahamas verifies this analysis, showing 15-30 kt southwesterlies from 450-250 mb. Additionally, microwave imagery seems to allude to lower level dry air wrapping in from the north. A sprawling circulation like Maria's can easily entrain dry air.

[StormSkeptic]

I think another factor is that water temps are at the most marginal in the area 79-80 based on a couple of the buoys. This combined with the dry air is not allowing enough instability to produce sustained deep convection. The relatively flat pressure gradient is also preventing Maria from building a tighter inner core.

Her eyewall is decaying

Looks very disorganized hope the trend continues.
