It's mostly jungle right now where Iota is, so we likely won't get any core measurements. There are a few communities about 50-75 miles inland though. Most of Nicaragua's population is in the mountainous regions and on the Pacific side, so while the wind damage may not be as big of an issue, the flooding (especially from rainfall) certainly will be.

The storm rages on....I don't know about yall.... but im ready for some of them blue skies for a change...It's quiet here .. think im gonna join yall.... and crash..... Goodnight Ice.... And all y'all!

If Iota remained a CAT 5 at landfall, it would have broken the record for latest Atlantic CAT 5 landfall by almost a month. The current record is held by the 1924 Cuban Hurricane which struck western Cuba as at CAT 5 on October 19. Thankfully, Iota wasn't quite as strong at landfall but still very dangerous. Hope Central America is pulling through.

From NHC 4 AM disco -

Due to the previous damage caused by Eta, wind reports have been
extremely limited. There was an amateur radio report from Club de
Radio-Experimentadores de Nicaragua of 124 mph (200 Km/h) winds and
roofs damaged in the town of Wilbi, Nicaragua. However, it is
uncertain if these were sustained winds or wind gusts. At the Puerto
Cabezas, Nicaragua, airport at 0253 UTC, a sustained wind of 72 kt
(134 km/h) and a gust to 98 kt (182 km/h) were measured. The initial
intensity of 90 kt is based on the Decay-SHIPS model's weakening
rate for inland tropical cyclones, and the remnant eye feature
still noted in infrared satellite imagery.

Inland loop of Iota:

Iota's center has now reached the mountains of western Nicaragua. Typically, a strong hurricane will lose half its intensity in 11 1/2 hours over land (flat land). Max winds are likely down to 55-60 kts now (possibly lower). The center will be fully over mountains by this afternoon, which should quickly weaken it to a remnant low. The threat is shifting from wind to very heavy rainfall today.

The 18z best track point yesterday was revised down to 135 kt, which seems like the right call based on what recon was reporting through the day. 12z remains 140 kt.

That's terrible for them...what a disaster

[alanstover]

Is there any readily accessible data on current rainfall rates or accumulative rainfall for Central America?
Thanks.

Not surprised at all to hear this. I made the comment last night after the 0z intermediate advisory that the would likely bump that down to Cat 4 and probably 18z as well. I knew they’d keep 12z as Cat 5 because that’s obviously when we got the strongest recon data.

Probably epic. I hope these people got away from the coast.

That is awful, I feel terrible for that community...

[bob rulz]

Wow. That reminds me a lot of what Dominica looked like after Maria.

[msbee]

Wow. That reminds me a lot of what Dominica looked like after Maria.

It’s also what St Maarten looked like after Irma.
I am feeling for those people.
So sad. So much destruction.

[cycloneye]

Those images revive my memory of what happened in Puerto Rico after Maria strucked.

I can imagine the death toll is going to be high on top of COVID-19 pandemic.
