TROPICAL STORM ARTHUR SPECIAL ADVISORY NUMBER 1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL012008
100 PM EDT SAT MAY 31 2008
…TROPICAL STORM ARTHUR…FIRST STORM OF THE 2008 ATLANTIC SEASON…QUICKLY FORMS NEAR THE COAST OF BELIZE…ALREADY MOVING INLAND.
Tropical Storm Arthur formed yesterday, and has deteriorated enough to now be ‘just’ a Tropical Depression.
It’s not all that unusual to have a named storm before the official opening of the hurricane season. I don’t draw any inference from that. However, with “A” given to a minimal storm, the season takes one quick step toward being more active than usual.
That brings up a great point made by Jeff Masters at Weather Underground.
Would Arthur have been named 30 years ago?
Arthur is one of those weak, short-lived tropical storms that may not have been recognized as a named storm thirty or more years ago. Arthur was named primarily based on measurements from a buoy that didn’t exist 30 years ago, and from measurements from the QuikSCAT satellite, which didn’t exist until 1999. There was one ship report that was used, though, and ship reports were heavily relied upon in the old days to name tropical storms.
I’ll answer his rhetorical question: Of course it wouldn’t have been named.
This is something many meteorologists point out to those who worry about an evolving atmosphere. As weather observations become more sophisticated, historical averages become that much less meaningful.
