CPAC: ISELLE - Post-Tropical

[Frank2]

Okay, folks, stop jumping down my throat - poor message board manners here admin...

P.S. Ask any NHC forecaster and they will tell you the same - using the word dangerous can be especially misleading if they downgrade this system on the next advisory (also known as confusion)...

Also, have you been in sustained hurricane winds? Those are definitely dangerous, even at Cat 1 level. Heck, tropical storm winds can still be dangerous.

Strongest winds I've been in were Sandy's and those were mostly around strong tropical storm force at their peak in gusts (65-70mph) and those were very frightening so I can't imagine true hurricane sustained winds.

I'm telling you guys... my 1979 built house starts to rock back and forth when gust reach 25mph. Imagine sustained winds with higher gusts.

Be safe.

[RL3AO]

Back on topic please. Frank made a decent point and a number of you disagree with his point. Leave it at that please.

I would think that the higher elevations in the Big Island of Hawaii would see much higher winds than what is estimated surface winds to be closer to the flight level winds.

But aren't there less people and structures higher up?

No, no. I have to respectfully disagree.

A LOT of people live on the mountains and high up in the valleys. Rent is cheaper there.

And those houses almost always take beatings from rainfalls since they're so high up. This is speaking from experience. We used to live in Kalihi valley and it would never stop raining. Our aluminum/steel roof tops were very rusty.

Will Iselle bring a threat of any landslides?

Many of Hilo's residential neighborhoods are above 400' in elevation with direct exposure to the east. Pahoa is at 700'. The string of town along Highway 11 leading inland toward Volcano are anywhere between 1000-4000' in elevation. I'd say you have more people living at elevation than near sea level.

Possibly, yes. The threat of landslides will become even more real if Julio was to threaten the islands. Ground would be saturated.

I would agree. Especially on the big island. I'm most worried about Volcano myself.

Likely some, but it is moving somewhat fast.

IIRC during Hurricane Tomas (2010) in St. Lucia, it was a Cat 2 but the winds were much stronger in the elevated areas of the island...damage more typical of a Cat 3 or 4 resulted.

[Yellow Evan]

To me knowledge, no. Most ppl live anywhere from 500-2000 feet in elevation AFAIK.

These ares could easily get Cat 2-force gusts.

How high is that?

Final approach for Iselle.

That was about 1,000 to 3,000 feet.
