Despite Tech, Tracking Storms Is Tough

Aug. 16, 2004 -- -- Every 30 seconds when a hurricane threatens, a U.S. Air Force Hurricane Hunter sends a burst of data to computers tracking the storm.

An Air Force C-130 was the first to signal that Hurricane Charley had become a category 4 powerhouse on Friday. The planes make multiple passes through the storm's eye, dropping probes into the air to measure wind speed, barometric pressure, and the temperature of the air and the water below it.

But despite the technology available today, Charley proved how difficult the art of forecasting can be.

"With hurricanes, each one has its own personality," said Lt. Col. Ron Marx, pilot of a hurricane hunter flight out of Keesler Air Force Base in Mississippi. "Even if we fly in the same one multiple times, every time we go it's different."

Hurricane Charley was a stern reminder of that. As late as Friday morning, some forecasts said there was a good chance the storm would hit Tampa, Fla., directly. But at the last moment, it made a slight turn to the right.

The storm's path only shifted about 50 miles, but to people in that path, those 50 miles were crucial.

"I never thought it was going to come right straight across and hit us like this," said one storm victim.

We'll Never Have a Perfect Forecast

Forecasters themselves know better than to be surprised by the last-minute surprises every storm offers. They issued hurricane warnings for the entire west coast of Florida the day before landfall.

"Hurricanes make these kinds of wobbles all the time," said Ed Rappaport, a meteorologist at the National Hurricane Center in Miami. "It's another reason why the warning area is larger than the storm itself."

The hurricane hunters send data from the storm's center, while satellites provide views from above. The information is analyzed by more than half a dozen different computer models.
