0-to-60 mph -is it a turbo-charged V8 or mother nature

It takes some of the better sports cars out there about 5-7 seconds to go from 0 to 60 mph.
Mother Nature showed off some of her own powerful accelerations during a storm that spawned an incredible gust front in Maine in June 2011
Michael McCormack has a web camera situated at Sebec Lake. About 1:45 p.m., a strong gust front went through the region, and the winds went from near calm to roaring over 60 mph in seconds.
And his web camera was rolling the entire time.
Here is how he described it:
"This image sequence shows a gust front approaching and raising a lot of water from the lake surface. The 4th frame shows a boat being overtaken at the leading edge of the wind. Last image shows a treetop landed in front of the cam." He estimates based on the speed of the front, the winds were blowing at about 66 mph at the leading edge.

Here are the images he was talking about. They are taken 30 seconds apart.

    Seattle Waterspout

    Waterspout Hits Southern Puget Sound:

    First Tornado Warning Here in 17 Years

    On Saturday around noon, several of you were startled to get a tornado warning on your smartphones.

    The cause: a waterspout that developed near Anderson Island in the southern Sound and which remained intact for about a half-hour. Here are some pics I found on the KOMO and KING-5 web sites. An extremely well-formed funnel and you can see from the first that the winds reached the surface, kicking up lots of spray.                            Beautiful pictures:
    Waterspouts are the weaker cousins of the strong tornadoes one finds over the Midwest U.S.
    According to the official Storm Prediction Center definition:

    A waterspout is a tornado over water--usually meaning non-supercell tornadoes over water. Waterspouts are common along the southeast U. S. coast and can happen over seas, bays and lakes worldwide. Although waterspouts are always tornadoes by definition; they don't officially count in tornado records unless they hit land. They are smaller and weaker than the most intense Great Plains tornadoes, but still can be quite dangerous. Waterspouts can overturn boats, damage larger ships, do significant damage when hitting land, and kill people.

    This waterspot, and virtually all of our waterspouts/tornadoes around here, are associated with non-supercell thunderstorms. Supercells are the big Kahunas of the thunderstorm world with very high tops (reaching 40-60K ft), intense rain, hail, and most importantly rotation.

    This waterspout came out of a relatively wimpy NW thunderstorm.
    Impressive for around here. But equally strong thunderstorms were hitting in the north Sound with no waterspouts. No sign of any hooked echoes...which indicate supercell storms.

    SPACE WEATHER - Minor Storm Warning

    MINOR STORM WARNING: A slow-moving CME propelled toward Earth by an erupting magnetic filament on the sun is expected to arrive today, Sept. 17th. NOAA forecasters estimate a 50% chance of minor geomagnetic storms in response to the sluggish impact. High-latitude sky watchers, be alert for auroras. Aurora alerts:textvoice

    Active Space Weather - incoming CME

    CME is an acronym for Coronal Mass Ejection. Think of it as a solar flare - on an enormous scale.

     DUAL CME: Another CME is en route to Earth. It was launched in our direction four days ago by the eruption of a magnetic filament near the center of the solar disk. This movie from the Solar and Heliospheric Observatory shows the Earth-directed CME almost overwhelmed, visually, by a brighter farside CME headed in the opposite direction.

    The impact won't be as effective as the double-blow Earth experienced on Sept. 12th, when two CMEs hit in less than 24 hours. Nevertheless, NOAA forecasters estimate a 50% chance of polar geomagnetic storms on Sept. 17th when the CME arrives. (Note: Yesterday we wrote that the CME would arrive on Sept. 16th, however, a revised analysis of its speed suggests a later arrival.) High-latitude sky watchers should be alert for auroras.
