The cone of error for Bill, however, is several hundred miles wide for days three to five in the forecast and all coastal residents in the eastern United States should continue to monitor Bill this week.The National Hurricane Center (NHC) has discontinued advisories on Ana and Claudette. Ana could still be a rain-maker for the Florida Keys and Southwest Florida on Wednesday and Thursday, but is expected to break up as it moves over the rugged terrain of the island of Hispaniola overnight.The next update on Hurricane Bill by the NHC will be at 11 p.m.
