Dennis strength..

[Josephine96]

Just a simple question of sorts here..

If Dennis is already @ 130 mph.. How strong could he possibly get..? Or will he not get much stronger since he has to pass Western Cuba 1st..?

[beenthru6]

I did hear Steve Lyons say that they hadconfirmed a 140mph wind gust in the ne quadrant of Dennis.

[Radar]

I dont think he is going through just Western Cuba it looks as though he will hit Central Cuba dead on. I suppose if Cuba doesnt slow it down it could be a Cat 4 or Cat 5 before making a landfall again in the US

[Josephine96]

That's a lot of wind..

[nolecaster]

We still do have a long wy to go to get to Cat 5. Remember it has to be absolutely perfect to support a Cat 5. I guess it could happen, but it's probably unlikely.

[Josephine96]

No Cat 5's please

[feederband]

What the equation for getting what the mph is from kts. I think I ask this every year..

[gkrangers]

No Cat 5, not with this storm.

Cat 4 hits Cuba, weakens to Cat 2 over Cuba, and strengthens to a strong 3 in the gulf.

Thats my call given the current setup...

[Mattie]

A loose translation - - - (there is a mathmatical formula)

45 KT = 50 MPH, 50 KT = 60 MPH
80 KT = 90 MPH, 85 KT = 100 MPH
110 KT = 125 MPH, 115 KT = 135 MPH*
145 KT = 165 MPH, 150 KT = 175 MPH

[weatherlover427]

I think it's 1.15 mph = 1 kt or something like that, could be reversed though...

Go to http://www.google.com . If you want to know what say, 88 knots is in mph, type this in the search bar:

88 knots in mph

and Google will make the conversion for you. Very handy. There's also lists of knots to mph conversions for almost all values for tropical storms to cat 5 canes but I can't remember the link.

[BamaMan]

Go to this site and it will give you a Knot to MPH calculator. Handy

Thanx every one...

Multiply knots by 1.1515151515151515



Its easy to remember. Just remember 1 dot 15 15 15 15 15 15 15

[Josephine96]

Yeah.. easy to remember if you're a mathematics major lol

[canegrl04]

My call on Dennis- he weakens to cat 2 after crossing Cuba,then hits the US at cat 4 strength

[soonertwister]

Dennis is going to make two landfalls in Cuba. The first landfall is imminent, on a peninsular spur on the south side of the island, south and west of Manzanillo.

Dennis is going to cross Cuba well east of Havana. I do not perceive that as good news for Florida.

That is incorrect. The formula carried out to several decimal places for each knot is 1.150779448 miles. A "per" suffiix implies speed.

That conversion factor is recent, from the U.S. Department of Commerce's National Institute of Standards and Technology, Boulder Laboratories, Boulder, Colorado.

It is the epicenter of world measurement standards, and it is less than one mile from my home.

Multiplying knots by 1.15 is perfectly acceptable and more than accurate enough for hurricane wind speed, since the NHC always assigns a wind speed rounded down to the nearest 5 knots for every advisory.

Any higher level of precision is worthless, since your working data isn't nearly as precise. Winds are variable and depend on many factors. Estimating to a greater accuracy than 5 knots is not only unnecessary, it's confusing.


Edited to change "world standards" to "world measurement standards"
Edited, minor grammatical correction.

Which also mean the flight level windspeed in knots is about the same as ground level windspeed in MPH, within +- 5%.

[Hurrilurker]

If you run Mac OS X Tiger, there is a built-in Dashboard widget called Unit Converter that is extremely handy for this stuff. It can convert all kinds of hurricane-related stuff, such as nautical miles ("knots" in terms of per hour) to miles to kilometers, celsius to fahrenheit, millibars to inches or centimeters of mercury to atmospheres, etc.

Another cool thing you can do is open up multiple World Clock widgets. I have one for my time (PST), one for U.S. East Coast time, and one for UTC/"Zulu" time. There are also widgets for collecting and viewing satellite imagery, NHC discussions, Doppler radar, and other fun stuff that I haven't had time to play around with yet. Check them out here.
