Every Part Of The Danny Forecast Relies On Guesswork

When the initialization is bad everything that follows it is suspect. Take the forecast with a healthy grain of salt.

It’s a little early for the late guidance on Danny, but not too early to tell you my worry. All day long the Hurricane Center has had trouble finding the center of the storm. Here’s what they said at 11:00 AM.

THE EXPOSED LOW-LEVEL CENTER HAS BEEN MOVING ALMOST DUE WESTWARD FOR THE PAST FEW HOURS. IT IS UNCLEAR IF THIS IS REPRESENTATIVE OF THE ACTUAL MOTION OF DANNY OR A SHORT-TERM TREND. SO…THE INITIAL MOTION IS AN UNCERTAIN 310/11.

They’re saying it’s moving west, but they’re officially marking it as northwest. Got it so far?

The latest technical discussion just hit a few minutes ago.

THE CENTER MEANDERED ABOUT DURING THE DAY…BUT LAST-LIGHT VISIBLE IMAGERY AND DATA FROM THE AIRCRAFT INDICATED THAT A NORTH TO NORTH-NORTHWESTWARD MOTION BEGAN SEVERAL HOURS AGO. HOWEVER…THE CENTER IS NEARLY IMPOSSIBLE TO DISCERN ON RECENT INFRARED IMAGES. THE INITIAL MOTION IS AN UNCERTAIN 330/7.

When the initialization is bad everything that follows it is suspect. Take the forecast with a healthy grain of salt.

The only good news is Danny continues to be a wimp. It wouldn’t take much to knock him out… nor much for him to rapidly intensify.

Earlier this evening my friend Bob, a professor of meteorology and tropical weather expert said, “I think it either remains a TS or becomes cat 2/3. I don’t think there is an in between.”

He’s probably right, but that’s not much help either!
