Hurricane Arthur
« on: June 30, 2014, 11:20:33 PM »
The Atlantic is alive!  Our first tropical depression has formed.  Based on the projected path, the system could become a Tropical Storm very soon and would be named Arthur.  The system may also skim the East Coast, so we'll have to watch out for this over the next few days.

My area (Daytona Beach) is already under a tropical storm watch.  TWC's cell phone alert got to me about 10 minutes (!) before NOAA Weather Radio broadcast the alert.

11 AM EDT update shows we have TS Arthur.  Max sustained wind 40 mph.  Now could become a hurricane by 8 AM Friday based on latest forecast.  East coast needs to watch this closely.

A lot of people are comparing Arthur to Alex (2004). Still too soon to say for sure how strong Arthur will really get, but it'll be interesting to see if Arthur ends up being a stronger hurricane than predicted.

Arthur is quite an amazing storm to watch develop right now. Right now, it looks like the convection is aggressively fighting back some minor dry air intrusion that affected Arthur last night and it's finally starting to wrap around all quadrants of where the eye is. I think the final stage would be for Arthur to establish a solid eyewall around the eye and who knows for sure what will or may happen after that... :whistling:

I put the chance of Arthur going through a RI (rapid intensification) period over the next 12-18 hours of about 30%.

I don't think there's anyone here who lives along the Outer Banks of NC (or slightly inland from there), but I'll ask anyway. Does anyone know whether or not they plan to do voluntary or mandatory evacuations out there? If not, I hope they are considering it (at least the voluntary evacuation) because Arthur will be passing near or through the area on the 4th of July. It wouldn't be safe to have tourists or residents out at the beaches as this likely to become hurricane is blowing through, even if it is only a Cat 1 (possibly borderline 2 at the worst)

Arthur is beginning to look a lot more symmetrical now on the visible satellite. Even the eye (which appears to be smaller) is appearing again as well.

Surprisingly, Arthur is still a tropical storm per the 11 PM EDT update, with max sustained winds of 70 mph.  Arthur is still expected to develop into a hurricane later tonight or early tomorrow, however,

While this should probably come as no surprise, Arthur is now a hurricane with max wind speeds of 80 mph. The title of this topic has been updated to reflect that.

Our first hurricane of the Atlantic season!

Gaining momentum, movement is NNE at 14 mph, winds have increased to 90 mph (just shy of Cat. 2 intensity) and pressure down to 981 mb per 11am advisory.

NHC is now projecting Hurricane Arthur to become a Category 2 hurricane as it approaches Cape Hatteras and the Outer Banks region.

Also if you want to look at a radar perspective of Hurricane Arthur's eye as it approaches NC, here's a great link
