WASHINGTON -- National Hurricane Center Director Max Mayfield testified before Congress again Friday.

Mayfield, along with other National Oceanic & Atmospheric Administration officials are explaining their role in hurricane predictions and how to approve upon them in light of Hurricanes Katrina and Rita.

Mayfield said the National Hurricane Center was pretty accurate about landfall and intensity forecasting for both storms.

He said the battle has just begun, with the prediction of more active hurricane seasons to come for the next 10 to 20 years, or even longer.

"Katrina will not be the last hurricane to hit a vulnerable area, and New Orleans is not the only area at risk to a large disaster from a hurricane. Galveston, Houston, Tampa Bay, southwestern Florida, the Florida Keys, southeastern Florida, New York City and Long Island and, believe it or not, New England, are especially vulnerable. And, of course, New Orleans will be hit again by a hurricane someday," Mayfield said.

There have been 19 tropical storms this season and 10 hurricanes. Hurricane season ends in seven weeks.
