Hurricane forecasters now have two storms to watch: Hurricane Katia could be on its way to becoming a category 3 storm, while a storm system in the Gulf could organize into tropical storm Lee within 48 hours.
Katia is set to become a category 1 hurricane Wednesday and could be a category 3 Sunday. But the track gives little hint of whether tropical storm Katia will hit the US.
Tropical storm Irene illustrates improvements that forecasters have made in forecasting a hurricane's track. But it also highlights needed improvements in forecasting storm intensity.
Hurricane Irene could gain some strength over the day, but the storm is likely to quickly weaken again as it heads north toward more populated areas of the mid-Atlantic and New England.
The track for hurricane Irene has the potential Category 3 storm crashing into the US near Beaufort, N.C., where officials are pleading with residents to evacuate.
Hurricane Irene weakened to 110 m.p.h. winds, but Irene is expected to strengthen to a Category 3 hurricane again is it reaches North Carolina
Coastal residents from Surf City, N.C., to the Virginia border should be ready for hurricane conditions within 48 hours, forecasters said Thursday morning. Irene is still a Category 3 hurricane, but it has broadened.
Hurricane Irene, with winds of 120 m.p.h., is now on a track to make landfall in North Caroline, then move toward New York and New Engalnd.
Hurricane Irene is now headed for North Carolina after pummeling Caribbean island nations from the Bahamas to the Dominican Republic, causing some $3.1 billion in damage.
