From Jeff Lindner this monring...

Effective May 15, 2010, Tropical Cyclone watches and warnings for the Atlantic and eastern Pacific basins will have lead times increased by 12 hours. Watches will be issued 48 hours before the onset of adverse conditions and warnings 36 hours. Additionally, effective this hurricane season the revised Saffir Simpson Hurricen Wind Scale will be operational. All storm surge and flooding effects related to hurricane SS category have been removed from this scale. NHC advsisories will report projected storm surge values as above ground levels instead of above sea level and indicate an area of inundation from the storm surge to help allivate confusion and help reduce the need for coastal residents to know their ground level elevations.
