    Danny fizzles, but a new threat emerges in the Atlantic 

    Fortunately for the coast, Tropical Storm Danny never quite got itself together, as strong wind shear and cooler water temperatures did it in. It brought some surf to the area and a bit of a rough storm to New England, but it certainly did not pan out as the Category 1 hurricane first predicted.

    NHC has shifted its attention to an area of disturbed weather (classified as Invest 94) about 800 miles to the east of the Windward Islands; they’ve marked this area as having a high chance of developing into a depression in the next day or two. There’s a broad circulation there; if it closes up, we’ll have something to keep an eye on as it moves westward. If it develops sufficiently and reaches tropical storm status, its name will be Erika.

    Tropical Storm Danny forms 

    NHC confirms: Tropical Storm Danny has been born. Danny’s packing 45 MPH winds and is moving west-northwest at 18. We’ll need to watch this as it stands to come fairly close to the Southeast coast by this weekend. The forecast calls for a Category 1 Danny to come very close to the Outer Banks of North Carolina Saturday morning. This can and likely will change as time goes on, so we’ll be keeping a close watch. Stay tuned.

    Danny likely to form today 

    We’re likely to see Tropical Storm Danny form today east of the Bahamas. Satellite imagery and the latest NHC outlook indicate a circulation has come together from the trough of low pressure. Last night a Hurricane Hunter aircraft went into the storm and found tropical storm-force winds within the wave.

    Given its proximity to the coastline, interests on the Southeast coast — including Charleston — need to keep a very close watch on this one. Computer model runs indicate that the Outer Banks, in particular, could get a sideswipe from Danny.

    More when I’m not writing from a BlackBerry…

    Bill is starting to deteriorate; and another wave to watch 

    Hurricane Bill’s been well-enveloped in its northerly turn around the high pressure in the north Atlantic and is beginning to encounter much more unfavorable conditions. Bill’s roughly located several hundred miles off the Outer Banks of North Carolina, and is packing 100 mph winds.

    The story from Bill for Charleston, of course, is high surf and rip currents. It’s a thrilling but dangerous proposition for surfers, as the strong rip currents can sweep people out to sea. High Surf Advisories continue through 6PM Sunday.

    Meanwhile, NHC is monitoring a wave off the coast of Africa for development; however, the latest tropical weather outlook shows the wave heading into an increasingly unfavorable atmosphere; unless it gets very organized within the next day or so, chances are pretty low that it will get it together enough to be a depression.

    Big Bad Bill strengthens, gains major hurricane status 

    Hurricane Bill reached major hurricane status overnight; as of the 11am advisory, Bill’s packing 135 MPH winds and maintaining a west-northwest trajectory at 18 MPH, putting it on a path to head just north of the Leeward Islands and west of Bermuda.

    The prognosis for us in Charleston is still very positive, as the computer models are in great agreement that Bill will start a turn to the northwest at some point tomorrow, and then turn gradually northward as it interacts with a trough of low pressure pushing its way off the Eastern Seaboard. While we’ll very likely be missed, the track could get a bit hairy for New England and Nova Scotia closer to this weekend. Folks up that way will want to keep an eye on Bill.

    Thankfully, aside from Bill, the tropical Atlantic is quiet, with nothing else in the train right now. I’ll continue to monitor and update as needed.

    Shallow coastal flooding expected this evening, through the weekend 

    We’ve got a double-whammy of coastal flooding possibilities through the weekend: high astronomical tides, and then some rough surf from Hurricane Bill closer to the weekend. A Coastal Flood Advisory is in effect tonight, and I suspect we’ll see one of these a day through the weekend:

    THE NATIONAL WEATHER SERVICE IN CHARLESTON HAS ISSUED A COASTAL
    FLOOD ADVISORY…WHICH IS IN EFFECT FROM 6 PM TO 9 PM EDT THIS
    EVENING.

    ASTRONOMICAL HIGH TIDES AS A RESULT OF THE PERIGEE TONIGHT AND THE
    NEW MOON EARLY THURSDAY…WILL PRODUCE WHAT ARE REFERRED TO AS
    PERIGEAN SPRING TIDES THIS EVENING.

    TIDES IN CHARLESTON HAVE BEEN RUNNING AROUND 1/3 TO 1/2 FOOT ABOVE
    PREDICTED TIDE LEVELS THE PAST SEVERAL TIDE CYCLES…AND THIS
    TREND WILL CONTINUE THIS EVENING. THIS WILL PRODUCE AN HOUR OR TWO
    OF MINOR NUISANCE FLOODING AT LOCATIONS NEAR AND ALONG THE COAST
    OF SOUTHERN SOUTH CAROLINA…AROUND THE TIME OF HIGH TIDE. THE
    HIGH TIDE THIS EVENING OCCURS IN CHARLESTON AT 703 PM AND AT
    BEAUFORT AT 818 PM.

    TIDES ARE EXPECTED TO REACH AS HIGH AS 7.0 TO 7.2 FEET MEAN LOWER
    LOW WATER AT CHARLESTON WITH THE UPCOMING HIGH TIDE.

    SOME COMMUNITIES SUBJECT TO SHALLOW COASTAL FLOODING INCLUDE…PARTS
    OF DOWNTOWN CHARLESTON SUCH AS LOCKWOOD AVENUE AND AMERICA
    STREET…LONG POINT ROAD IN MOUNT PLEASANT NEAR BOONE HALL
    CREEK…SULLIVANS ISLAND…FOLLY BEACH…EDISTO BEACH AND FRIPP
    ISLAND.

    We’ll begin to feel Bill’s waves this weekend. An excerpt from this afternoon’s Hazardous Weather Outlook:

    LARGE AND POWERFUL…LONG PERIOD SWELLS GENERATED BY HURRICANE
    BILL WILL REACH THE BEACHES OF SOUTH COASTAL SOUTH CAROLINA AND
    NORTH COASTAL GEORGIA OVER THE WEEKEND. THIS WILL RESULT IN AN
    ENHANCED RISK FOR RIP CURRENTS ALONG AREA BEACHES.

    TIDES/BEACH EROSION…SHALLOW COASTAL FLOODING WILL REMAIN A
    POSSIBILITY WITH THE EVENING HIGH TIDES THROUGH THE WEEKEND AT
    THE COAST. IN ADDITION…THE COMBINATION OF POWERFUL SURF AND HIGH
    ASTRONOMICAL TIDES COULD PRODUCE MINOR TO MODERATE BEACH EROSION
    AT AREA BEACHES…MAINLY THIS WEEKEND.

    It’ll be a great weekend for surf, but also a dangerous weekend in the water, especially for inexperienced swimmers. Typically with tropical system-generated surf, swimming restrictions go into effect, and I have a feeling that will happen this weekend.

    Bill continues to strengthen, but still expected to miss 

    Editor’s note: Expect a daily briefing around noon/early afternoon as Hurricane Bill continues to spin out in the Atlantic. This blog will primarily focus on Bill’s potential effects on Charleston, SC weather. For the most up-to-date source of information about Bill and potential impacts elsewhere, please visit The National Hurricane Center website. If Bill makes a move that more directly threatens Charleston, coverage will increase.

    Hurricane Bill, a Category 2 storm with 105 MPH winds, is continuing to spin out in the Atlantic. It’s formed a pretty well-defined eye this afternoon after an early-morning eyewall replacement cycle; at this point, it’s safe to say it’s clear for more strengthening. The official NHC forecast does place Bill as a major Category 3 storm within the next 24 hours.

    Fortunately for the U.S. East Coast, Bill is expected to begin to recurve out to sea within the next few days. All the forecasting models are in good agreement about Bill’s recurvature out to sea. Where it recurves is another matter; there are some solutions that seem to push Bill fairly close to Maine later on in the week as it becomes extratropical. Interests on Bermuda are also watching Bill’s recurvature closely; the models range from a sideswipe of the island to a more direct hit. The forecast track seems to favor a bit of a glancing blow to Bermuda. However, the cone of uncertainty around the track is incredibly large, with a lot of room for error, so this is still something to watch, especially before it crosses the 32nd parallel.

    An East Coast landfall is quite unlikely; however, that doesn’t mean Bill’s effects won’t be felt here. We should start to see some fairly good surf in the next day or so as Bill begins to recurve and parallel the coast. With that surf, though, comes an elevated rip current risk, so be careful if you look to catch the waves. Keep an eye to Surf Lowcountry if you’re looking to hang ten.

    Keep watching Bill — tropical systems are still unpredictable, after all. If things change, we’ll jump in here or on Twitter.

    Welcome to hurricane season! Technically, this has been going on since June 1, but with only a short-lived tropical depression to speak of, the first two and a half months of the 2009 Atlantic season has not exactly been in the forefront of everyone’s mind.

    That’s changing, though. Tropical Storm Ana formed this morning, with Tropical Depression Three right behind it (expect it to become Bill soon). Where are they headed? While it’s too soon to say for sure, these two are storms we’ll want to keep an eye on in Charleston. (More …)

      Please make the date more prominent on this weather page.

      I was reading along and happened to glance up at the tiny date and saw it was 3 days ago.

      Not too impressive when seeking internet “instant” updates.

      Thanks.

      Thanks for the feedback, Chuck. The design’s still very much in flux; I have a lot more work to do with it, but limited time to work with it.

      I’m not thrilled with my performance updating the site, either. Life does tend to get in the way. However, with Bill not likely to threaten Charleston, I’m hesitant to accelerate coverage and blow a storm spinning in the Atlantic out of proportion. I’ve added an editor’s note to the latest post to hopefully explain this editorial position a bit better. I also need to put the “don’t use for life or death decisions” disclaimer back in, too. :)
