MYRTLE BEACH, S.C. - Forecasters were able to
track Hurricane Isabel from its start as a tropical wave deep in the
Atlantic Ocean on its trek through the Caribbean, into North
Carolina and eventually Canada before the storm fizzled in the cold
northern air.
Along the way, they made predictions about where the storm would
be five days later. Although Isabel forecasters showed remarkable
accuracy - preliminary estimates show the storm made landfall about
200 miles from its original 5-day estimate - some along the coast
worry that long-term prognosticating can unnecessarily frighten away
tourists.
"In this case, the five-day track didn't hurt us," said Gary
Loftus of Coastal Carolina University's Clay Brittain Jr. Center for
Resort Tourism. "But the concerns are still there. I still think a
five-day window is too broad and unnecessary."
Traditionally forecasters have used a three-day model to help
officials determine when to evacuate an area. This season, that has
changed to a five-day forecast. Emergency planners say the extra
days are helpful, and the forecasters say the predictions were right
on mark.
"The model performed in excellent fashion," said Frank Lepore of
the National Hurricane Center. "It's serving the function for which
it was designed."
The long-term projections also offer a consistent forecast, said
Tom Matheson, the warning coordination meteorologist at the National
Weather Service in Wilmington, N.C. "It takes it out of the hands of
private meteorologists," he said.
Despite the accurate Isabel predictions, the five-day forecast,
which has an average margin of error of 340 miles, needs to be fine
tuned, said David Nolan, an assistant professor of meteorology at
the University of Miami.
"It is premature," Nolan said. "The average error is so large in
five days. But this time, the storm went right there. Everything
really worked out."
In the case of Isabel, South Carolina may have benefited when
early forecasts showed the storm would pass the coast. Estimates
from Coastal Carolina show just a 1 percent drop in occupancy along
the Grand Strand last week.
"It is a concern for people making their plans. Why take that
risk?" said Helen Hill, executive director of the Charleston Area
Convention & Visitors Bureau.
The Council of Myrtle Beach Organizations is leading a push to go
back to the three-day forecasts. "It was done without any public
input," the council's John McMillan said of the change. "It's
causing a lot of confusion."
The group will meet Oct. 20 in Myrtle Beach to discuss the
issue.
