still watching from the panhandle making sure it doesn't go due west anymore. it wouldn't shock me if that happened.

waiting on putting up hurricane shutters until late Saturday PM or early Sunday AM.  :roll:

If Irma gets to me as the five day track hints, it would be the third this year after Cindy and Harvey.

Hmmm, 2017, an anomalous year, ~1850-2017, an anomalous period; or the "New Normal"  :twisted:, hint hint .

You would think from that cam there's no storm coming.
Here's another live one from key west.

Strange video from Long Island in the bahamas. Storm pushed all the water out.
I have seen this in the past but on Lake Erie. A strong west to NW wind pushed all the water in the west end of the lake to the east. Never seen it in the ocean though.

When this happens you go fast and far away as you can.
Most memorable for me was the 2004 Indian Ocean tsunami sucking the beaches dry and people wandering around, most didn't make it.

Yes, Irma's beginning to lift away from the Cuban coast, a very slight bend in course northward.
How, and if, this course change holds and/or increases, will determine where it slices the Keys, and where it impacts the Florida coast.
Irma will be crossing the area where the Gulf Loop Current joins the Gulf Stream, and both are anomalously warm now, a significant intensification could be just hours away.
Irma could also possibly traverse and remain over the East part of the Loop Current, this link has a good write-up on how that has intensified many cyclones (as does the Gulf Stream).
Gulf Loop Current
All the models take it onto a WNW/NW/NNW/N course, but it's now clear the Irma will have an excursion to some degree into the Gulf of Mexico, where SST's (and positive heat anomaly) could affect that and certainly the intensity.

A wind-driven tidal movement is extremely common on many bodies of water, tsunamis are rare. The wind-water level effect is a constant factor in boat navigation. Lake Erie is a good example in extremis, Texas bays and barrier islands another. It works both ways, the water level can go down to nothing, or it can flood to record levels (on top of the normal tides).
Everything from launching a small craft from a ramp, to getting in and out of a slip and setting dock lines are affected by it. Let alone traversing 'skinny water' with a keelboat when the fetch of a brisk wind has taken a foot or four off the charted depths  :shock:.

With the trough bearing down from the NW, NHC and the models think that's highly unlikely.

Maybe premature, but the last few radar scans appear to have slowed, if not stopped the forward progress. Perhaps the trough influence is starting and the further right turn will commence shortly.

Check this out, first time I've ever seen this in my forecast.

MondayTropical storm conditions possible. A chance of showers and thunderstorms, then showers and possibly a thunderstorm after 7am. Some of the storms could produce heavy rainfall. High near 65. Chance of precipitation is 100%.

Monday NightTropical storm conditions possible. Showers and possibly a thunderstorm. Some of the storms could produce heavy rainfall. Low around 59. Chance of precipitation is 100%.

They're saying I could get about 4" of rain with gusts around 50mph or so. Gonna be nasty here!

I think you're right; the turn we've all been waiting for could be coming shortly. I just hope I don't lose power.

It looks to me like it's just sitting there thinking about where it wants to go.

A couple of stations I've been watching in the keys looks like they've lost power.  Here is one that is still transmitting at this time.

You can see the 'rain bands' coinciding with the passing of feeder bands as they passed over that location.

From its WU station. It says it read a 250mph wind gust.

Shocking. I remember a few years ago they had my dew point hotter than the surface of the sun. Not kidding. :roll:

Yeah, I think that's not going to pass the QA check.  But I never have been crazy about the way WU reports gusts.  It never seems to correspond with CWOP or PWS.
