Elementary School Day

October 31st, 2012 at 4:01 pm by under Weather

Meteorologist David Yeomans and I spent some time at two area elementary schools today. Thanks to the staff and students at Copperfield Elementary School in Pflugerville for inviting us out for career day.

And, David says he enjoyed talking about the weather with the 3rd graders at Fern Bluff Elementary School in Round Rock! We wish all of you a happy and safe Halloween! Don’t eat too much candy tonight!

Here is a 12 day animation of Hurricane/Superstorm Sandy–a storm that will likely enter the history books as the 2nd costliest natural disaster in U.S. history. Hurricane Katrina ranks 1st.


How Sandy became most powerful storm on record

October 31st, 2012 at 3:42 pm by under Weather

Sandy did not set any records with her peak wind speeds – only maxing out briefly at Category 3 status (115 mph) before impacting Cuba.  But she did set a record of a different sort.

A NOAA satellite image of Hurricane Sandy at 9:15am Central time Sunday, Oct. 28th.  At the time of this image, Sandy was a Category 1 hurricane with maximum sustained winds of 75mph.

Hurricane Sandy is now the most energetic tropical cyclone in history, due mainly to its massive wind field.

In technical terms, Sandy contained the most integrated kinetic energy of any storm in history – meaning if you add up all of the total energy contained in her incredibly large area of tropical-storm-force winds, as well as her smaller area of hurricane-force winds, there has never been a tropical cyclone in history that has contained more overall sheer power.

Sandy contained 311 terajoules of energy. Put more simply, that is 311,000,000,000,000 Joules! To put this into context, 1 Joule is about the energy contained in a tennis ball moving at 14 mph.

Clayton, W.Va.: 33.0″
Haywood County, N.C.: 24″
Norton, Va.: 24″
Mt. Leconte, Tenn.: 34″

POWER OUTAGES: CNN reported more than 7.5 million
By comparison, Hurricane Ike had 7.5 million over his entire path.

National Guard troops called out: On Tuesday, nearly 7,500 National Guard soldiers and airmen were on duty in Connecticut, Delaware, Maine, Maryland, North Carolina, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Virginia.

TOP STORM SURGES:
The Battery, N.Y.: ~9 feet above normal
Kings Point, N.Y.: ~12.5 feet above normal
New Haven, Conn.: ~9 feet above normal

Number of calls per minute to NYC 911 at height of the storm: As of Monday night, the 911 system was receiving roughly 10,000 calls per half an hour, according to WSJ.com. The typical volume is 1,000 calls per half an hour.

Evacuations: In New York City, 375,000 people were ordered to leave flood-prone zones ahead of the storm. On Tuesday, more than 3,600 people were at 76 shelters in New York City, which has 16,000 shelter beds.

Damage in Dollars:  Damage estimates have been put between $30 and $50 billion.

Sandy now a hybrid “superstorm”

October 29th, 2012 at 11:11 pm by under Weather

Hurricane Sandy has transitioned to a “post-tropical” storm, merging with a massive Nor’easter to create a hybrid “superstorm.”  Read about this transition here:

By ERIN McCLAM, Associated Press

ATLANTIC CITY, N.J. (AP) — Superstorm Sandy slammed into the New Jersey coastline with 80 mph winds Monday night and hurled an unprecedented 13-foot surge of seawater at New York City, flooding its tunnels, subway stations and the electrical system that powers Wall Street. At least 10 U.S. deaths were blamed on the storm, which brought the presidential campaign to a halt a week before Election Day.

For New York City at least, Sandy was not the dayslong onslaught many had feared, and the wind and rain that sent water sloshing into Manhattan from three sides began dying down within hours.

Still, the power was out for hundreds of thousands of New Yorkers and an estimated 5.2 million people altogether across the East. And the full extent of the storm’s damage across the region was unclear, and unlikely to be known until daybreak. (more…)

If you haven’t heard by now…. most likely you live under a rock.  Hurricane Sandy is expected to make landfall in central NJ later today, and will impact millions of families and homes over the next few days.  It is very rare that a storm stays so powerful this late in the season, this far north in the Atlantic.  It is even more incredible that it will join forces with a strong winter-like storm over the Great Lakes.  This combination will bring massive flooding, widespread power outtages, and even blizzard like conditions (Appalachans) to neighborhoods from Ohio & West Virginia to Massachusettes & New York.

Most, if not all major news outlets will be offerning “wall to wall” coverage on Sandy over the next few days if you would like to follow along.  Also, here are a few links to more coverage, blogs, and scientific parameters for all of you weather junkies out there to dive into more detail:

Hurricane Sandy the most energetic storm in history

October 28th, 2012 at 9:53 am by under Weather

Hurricane Sandy continues to steam towards the northeastern United States, potentially bringing a life-threatening situation to millions of people within the next 24 hours.

Sandy has not set any records with her peak wind speeds – only maxing out briefly at Category 3 status (115 mph) before impacting Cuba.  But as of this morning, she has set a record of a different sort.

A NOAA satellite image of Hurricane Sandy at 9:15am Central time Sunday morning. At the time of this image, Sandy is a Category 1 hurricane with maximum sustained winds of 75mph.

Hurricane Sandy is now the most energetic tropical cyclone in history, due mainly to its massive wind field.

In technical terms, Sandy contains the most integrated kinetic energy of any storm in history – meaning if you add up all of the total energy contained in her incredibly large area of tropical-storm-force winds, as well as her smaller area of hurricane-force winds, there has never been a tropical cyclone in history that has contained more overall sheer power.

Sandy contains 222 terajoules of energy. Put more simply, that is 222,000,000,000,000 Joules! To put this into context, 1 Joule is about the energy contained in a tennis ball moving at 14 mph.

A chilly night ahead

October 27th, 2012 at 6:24 pm by under Weather

Temperatures will fall quickly tonight with our mostly clear skies and calm winds. There is a Freeze Warning for Mason and San Saba counties until 9 a.m. Lampasas County is under a Frost Advisory until 9 a.m.

There’s also the chance for a little frost in the low lying areas of Central Texas tonight. If you have plants that are vulnerable, it’d be a good idea to cover them just in case.

Here’s more from the National Weather Service:

...PATCHY FROST POSSIBLE SUNDAY MORNING ACROSS NORTHERN HALF OF SOUTH
CENTRAL TEXAS....

EARLY SUNDAY MORNING WILL SEE THE COLDEST TEMPERATURES SO FAR
THIS EARLY FALL SEASON. CLEARING SKIES AND LIGHT WINDS WILL ALLOW
TEMPERATURES TO FALL INTO THE MIDDLE AND UPPER 30S ACROSS THE
NORTHERN HALF OF SOUTH CENTRAL TEXAS...INCLUDING THE HILL COUNTRY.
THE AREA THAT WILL SEE THE COLDEST TEMPERATURES SUNDAY MORNING IS
THE AREA MAINLY NORTH OF INTERSTATE 10.

THERE WILL BE SOME LOWER ELEVATIONS AND LOW LYING AREAS THAT WILL
LIKELY SEE THEIR FIRST FROST OF THE FALL SEASON. THERE IS EVEN THE
POSSIBILITY THAT ONE OR TWO LOCATIONS COULD EVEN DIP DOWN TO NEAR
FREEZING...ALTHOUGH THOSE COLDEST READINGS SHOULD BE FAIRLY
ISOLATED AND CONFINED TO RIVER VALLEYS AND AREAS NEAR CREEKS AND
STREAMS. IF YOU HAVE OUTSIDE TENDER VEGETATION THAT IS SUSCEPTIBLE
TO COLD TEMPERATURES...YOU SHOULD CONSIDER MOVING THEM INSIDE IF
YOU LIVE IN THESE LOW LYING AREAS.

THIS COOL WEATHER WILL CONTINUE EVEN INTO MONDAY MORNING WHEN
PATCHY FROST IS STILL POSSIBLE ACROSS MAINLY NORTHERN SECTIONS OF
SOUTH CENTRAL TEXAS.

LISTEN TO NOAA WEATHER RADIO OR YOUR LOCAL MEDIA FOR LATER
UPDATES ON THIS SITUATION.
