Re: Hurricane Issac Stalls!

I guess I need to check the definitions since I was counting land fall as any time any portion of the eye was over land, obviously that is not how the NHC is determining it.

According to NHC:

LANDFALL - The intersection of the surface center of a tropical cyclone with a coastline. Because the strongest winds in a tropical cyclone are not located precisely at the center, it is possible for a cyclone's strongest winds to be experienced over land even if landfall does not occur. Similarly, it is possible for a tropical cyclone to make landfall and have its strongest winds remain over the water. Compare direct hit, indirect hit, and strike.

That's pretty much what I was thinking it is. In this case, with that definition, the actual first landfall time could have been judged + or - 8 hours. What I used (right or wrong) if the storm has an eye wall, and land has made it inside the eye wall, then it has made land fall. Then again they may not have considered the long, very lightly populated, area of Louisiana, where the Mississippi outflows into the Gulf as real land.
