EPAC: TROPICAL DEPRESSION JIMENA (13E)

[x-y-no]

149 knots flight

[wxman57]

FWIW, I measured a 4-hr movement (15Z-19Z) of 309 deg at 9.5 kts. That's left of the forecast track.

[Solaris]

recon measured less than 930 mb in latest pass with flight winds well above 140 kts...could be a cat 5 at the moment

[CrazyC83]

Seems to be bombing out? Winds support 135 kt, pressure down to 926mb...

[Cyclenall]

Recon just got 149 knot flight level winds! What does 01 stand for on the last column to the right? Does this mean we have a category 5?

I also see the lowest pressure thus far found is 925.9 mb (round to 926 mb). The center splash found a slightly higher value. This is the most powerful hurricane so far this season (was there much doubt there anyways?).

149 kt at flight level = 134 kt, with SFMR of 132. I'd go with 135 kt for an intensity right now. It seems to be in its third intensification spurt.

[HURAKAN]

10 mb between passes. More impressive stuff.

135 knots certainly seems like a good estimate. But the difference in pressure between passes is sort of hard to believe - the next one should be very interesting.

931mb/7kt

[CrazyC83]

Dropsonde confirms a 931mb pressure. Still quite a drop but more reasonable.

[x-y-no]

wow ... has it really dropped over 5mb in this short time?

[CrazyC83]

135 knots certainly seems like a good estimate. But the difference in pressure between passes is sort of hard to believe - the next one should be very interesting.

I don't think there will be another pass, it is a long way back to the base.

[RL3AO]

I don't know if we will get another pass.

[craptacular]

Recon just got 149 knot flight level winds! What does 01 stand for on the last column to the right?

Those last two numbers are flags. A '01' means they question the temperature or dew point. If the second digit is anywhere from 2 to 9, then one or more of the wind speed readings are questionable.

[KWT]

Hmmm just goes to show its a very powerful hurricane, I strongly suspect the NHC will upgrade this post-season if this one doesn't make hurricane at the moment.

Eye is clearing somewhat again, so does suggest its strengthening.

I read it before but it's been a while since I've seen what 01 means. Thanks.

What do you mean here?

He means category 5.
