9/30-10/5 Joaquin-Trough Interaction-DISCUSSION/OBS

Even as Joaquin has been drifting southwest (225°) over the past 12 hours, the last 6 hours have seen a south-southwest trajectory (203°). Should that trajectory be sustained, the hurricane could be south and east of where the models place in in 12-18 hours perhaps making a capture more difficult.

I'm thinking it might try going for a late capture but could be too east to make much impact.

Love me some media hype.

 

BREAKING: Hurricane Joaquin Now Expected To Directly Strike N.J.

The storm strengthened to a Category 3 storm, packing 120 mph winds, with expected landfall by Monday.

:facepalm:

 

It's unbelievable the depths people will go to in order to drive traffic to their website. They don't even have the updated cone which shows a further East track.

And an unfortunate side effect of NHC taking a 'middle of the road' approach to guidance when they have very low confidence in the track. Perhaps they shouldn't even post long range forecast in such situations, because people don't understand.

The particular web publication's hype has nothing to do with the NHC. The NHC is taking a balanced approach until the picture becomes clearer. The NHC also provides the following caveat:

 

NHC tropical cyclone forecast tracks can be in error. This forecast uncertainty is conveyed by the track forecast "cone", the solid white and stippled white areas in the graphic. The solid white area depicts the track forecast uncertainty for days 1-3 of the forecast, while the stippled area depicts the uncertainty on days 4-5. Historical data indicate that the entire 5-day path of the center of the tropical cyclone will remain within the cone about 60-70% of the time. To form the cone, a set of imaginary circles are placed along the forecast track at the 12, 24, 36, 48, 72, 96, and 120 h positions, where the size of each circle is set so that it encloses 67% of the previous five years official forecast errors. The cone is then formed by smoothly connecting the area swept out by the set of circles.

 

It is also important to realize that a tropical cyclone is not a point. Their effects can span many hundreds of miles from the center. The area experiencing hurricane force (one-minute average wind speeds of at least 74 mph) and tropical storm force (one-minute average wind speeds of 39-73 mph) winds can extend well beyond the white areas shown enclosing the most likely track area of the center.

The NHC has done an excellent job handling this very difficult situation. It's not their fault a bunch of idiots are uploading false hype stories and misinformation.

Rich Nabb is doing a great job. And their cone is very reasonable. I would say 90% chance it's going to be right albeit on the right side but right.

Again even if it misses we have days and days of major surf and erosion. Remember Sandy never hit the otter banks but still did tremendous damage there

Long time lurker but I have a question. What happens if it continues to "wobble" W-NW? as others have stated the eruo had the southern edge of the storm into Cuba and that doesn't seem to be the case. What differences would that have down stream. I'm still learning as in going to school for meteorology. Thanks

The notion that the Euro is wrong is just so inconceivable at this point. Especially with 95% of the other guidance now leaning towards that solution. 

 

What's amazing is that not once has Florida even been considered in danger and the center will probably be only a few hundred miles offshore tomorrow.

What if ALL the models are wrong?
