I'm not an alarmist, but this is not heading in a good direction.

Ike: How much should we trust the three-day forecast?

We're now probably less than three days from Hurricane Ike, which now has 90 mph winds, making landfall along the Texas coast. The natural question to ask is, can we have confidence in the hurricane center's forecast near Port Lavaca?

There are several ways to answer that question. Foremost, we can look at the average error for three-day forecasts, and find that it's about 160 miles. Galveston is only about 130 miles from Port Lavaca.

Now we'll look at the forecasts for Katrina, Rita, Wilma and Gustav.

Hurricane Katrina

Date of landfall: Aug. 29, 10 a.m.

Actual landfall: Louisiana-Mississippi border

Forecast landfall: Fort Walton Beach, Fl.

Forecast error: 190 miles

Forecast winds at landfall: 115 mph

Actual winds at landfall: 125 mph

Hurricane Rita

Date of landfall: Sept. 24, 4 a.m.

Actual landfall: Johnson's Bayou, La.

Forecast location: Palacios

Forecast error: 200 miles

Forecast winds at landfall: 140 mph

Actual winds at landfall: 115 mph

Hurricane Wilma

Date of landfall: Oct. 24, 7 a.m.

Actual landfall: Cape Romano, Fla.

Forecast landfall: Bonita Springs, Fla.

Forecast error: 35 miles

Forecast winds at landfall: 100 mph

Actual winds at landfall: 120 mph

Hurricane Gustav

Date of landfall: Sept. 1, 8 a.m.

Actual landfall: Cocodrie, La.

Forecast landfall: Cocodrie, La.

Forecast error: 0 miles

Forecast winds at landfall: 120 mph

Now we'll look at the forecasts for Katrina, Rita, Wilma and Gustav.

All that stuff is just gibberish. They don't show when they got those predictions as opposed to the time of landfall. Forty-eight hours before Rita landed, it was not predicted to his Palacios.

If you want to go back in time, the predictions five days ago were for Ike to hit the east coast of Florida. So I guess you can say they have a 1,500 mile wrong prediction.

I don't start paying attention to predictions until the storm is less than three days out. Anything other than that is just to get people alerted.

Would someone give the % of Jefferson County losing power?

There is no way to even guess when we can't know where the storm will make landfall. If it stays on the current predicted course, we could see Edouard like conditions around here and maybe a little worse. How much lost power back in August when it hit?

Man this thing needs to move more west or we might be in trouble!! I have also noticed that all the models have moved more east. GFDL has it going right over Galveston Bay..

Shades of Rita.

In the words of Yogi Berra, this is like deja vu all over again.

Any idea of how much rain we can expect in the DFW area?   We have had a lot of rain the last two days and a severe downpour could cause major flooding issues.

I know my question isn't as important as what SE Texas is facing, but I just want to be prepared

Yes it could!

Rita did and I think it was Andrew in 1992 where we had our first mass evacuation as it was supposed to clobber us and it went so far east the last two days that we didn't get a cloud out of it.

May be tomorrow before it speeds up. I have landfall at Freeport Sat. Morning.

That said, what can we expect here in the triange if the storm hits in freeport???
