First TPC Wave of 2007

The NHC discussion mentions the first tropical wave of the 2007 season is on the tracking map this morning as the June 1 calendar start date looms. Here is the discussion.

..TROPICAL WAVES...

TROPICAL WAVE...THE FIRST TRACKED ON OUR SFC MAP IN 2007...IS
LOCATED ALONG 21W/22W S OF 10N MOVING W ABOUT 15 KT. THIS WAVE
APPEARS TO HAVE MOVED OFF THE AFRICAN COAST AROUND 06Z ON SAT
BASED ON SATELLITE AND SFC DATA OVER THE PAST FEW DAYS. THE WAVE

PLACEMENT WAS BASED ON LOW TO MID LEVEL CURVATURE SEEN ON NIGHT
CHANNEL VIS IMAGES WHICH ALSO SEEMED TO MESH WELL WITH A SHIP
AND BUOY REPORT SURROUNDING THE FEATURE. THE BUOY...CALL SIGN
31006...HAS BEEN PARTICULARLY HELPFUL SHOWING THE WIND VEER MORE
TOWARD THE E POSSIBLY INDICATING THE APPROACH OF THE WAVE AXIS.
HOWEVER...EARLY MORNING'S VIS IMAGERY SUGGESTS THAT THE WAVE
AXIS COULD BE FURTHER W BASED ON THE SHAPE OF THE LOW-MID LEVEL
CLOUD FIELD...SO THE FORWARD SPEED OF THE WAVE MIGHT BE CLOSER
TO 20 KT. THIS WEAK FEATURE IS LOW-LATITUDE AND IT'S MAIN
FUNCTION IS PERTURBING THE ITCZ SLIGHTLY. SCATTERED MODERATE
CONVECTION IS WITHIN 180 NM E OF THE WAVE AXIS.

As a reminder for what happened in 2006, here is the historic map.

Let the action begin.

Sorry for the lack of updates, I'm in the process of moving up to Southeastern Virginia (into the Hurricane Zone). I'll be updating soon. Gonna be watching the SPC for your chase updates. I'm so jealous.

Hey SCM,

Nice blog (and beautiful pictures)! I came across it just a little while ago and was hoping to find a way to email you about a new hurricane-tracking website I've been working on, but I didn't want to spam your blog with a URL. My email address is matthew dot wensing at-symbol yahoo dot com. If you have a moment, I'd love to get your two cents.
