Wireless Emergency Alerts. Love them? Hate Them?

Weather Emergency Alerts…you either love ‘em or hate ‘em. Either way these smartphone alerts are timely and efficient ways of getting important information to the general public.

iphone alerts

With the latest blizzard that struck NYC, millions of people received a message on their smartphones warning of the imminent road closures. Federal agencies (like the National Weather Service) and local governments are the only ones that can issue such alerts. They are sent through all major carriers at no cost to you.

There are strict guidelines, however, when government agencies can utilize this communication tool. They include:

  • Flash Flooding
  • Tornado
  • Tsunami
  • Hurricane
  • Extreme Wind
  • Dust Storm

Can you turn off these automatic alerts? Yes. But the potential benefits of the WEA’s could be life-saving.

Have you ever received a Wireless Emergency Alert? If so, did you find it helpful?

Say It Ain’t Snow! More Snow Coming for the Northeast

While parts of New England are still digging out from the one to three feet of snow they saw earlier this week, another storm system is on its way to potentially add to the misery.

Radar as of 2:15 PM ET January 29, 2015.

NAM model precipitation and pressure for 9 PM tonight (January 29, 2015)

We expect the storm system to continue to spread snow eastward throughout the afternoon and evening hours today, bringing with it enough to probably have to shovel your sidewalk and driveway tonight or Friday morning.

NAM model precipitation and pressure for 6 PM Friday (January 30, 2015)

However, as the low pressure system slowly moves offshore throughout the day Friday and into Friday Night, we’ll see an intensification in the snow over parts of northern New England. Due to this, over the next couple days, parts of Maine could end up with another foot of snow!

Winter Storm Warnings (pink) and Winter Weather Advisories (purple) as of 2:30 PM ET January 29, 2015.

Winter Storm Warnings are already in effect for the entire state of Maine for Friday into early Saturday due to the incoming snow. Local Weather Service offices are not only warning of the snow, but of some gusty winds as well – up to 30 mph at times – that will help to reduce visibility as the snow is falling.

Some areas of Maine could easily pick up 6-12″ of snow, and possibly more, as we head through Saturday evening. Amounts will taper off quickly as you head southwest, however, with 3-7″ possible in parts of New Hampshire. We’ll have to watch the gradient closely in the Boston area depending on how the snow sets up, but some of the suburbs could see 3-6″ into Saturday. Even further south than that, New York City and parts of southern New England will likely only pick up between 1-3″ from the system.

NAM model precipitation and pressure for Noon Friday (January 30, 2015)

After that, all eyes will turn to a system in the Southwest that could bring a foot or more of snow to the mountains of New Mexico. This system will move across the country this weekend, bringing rain and snow to parts of the Central and Southern Plains, as well as the Ohio Valley, Saturday and Sunday. After that, we’ll have to see what direction the storm takes, as the potential exists that it could bring even more snow for parts of the Northeast heading into early next week.

Unfortunately, the Waste Management Phoenix Open (PGA Golf) is going on this weekend in Scottsdale, AZ, so the last thing they want to see is rain! They will likely have to dodge a few raindrops throughout the day Friday and into Saturday as Tiger Woods makes his return to the course for the first time in 14 years. Sunday looks to be the bright spot of the weekend!

We’ll keep an eye on the snow chances for the Northeast over the next few days!

Was Northeast Blizzard Forecast a Bust?

The Grand Illusion

With apologies to the rock band Styx – I’m talking about a different illusion here. Recent years have brought a meteorological arms race: new weather models, higher resolution, more petaflops! Here is what I hear all the time:

“Paul, you blinking meathead, you have access to supercomputer and Doppler radar. You SHOULD be able to tell me exactly how many inches of snow will fall in my yard!”

In theory, yes. In reality, not even close.

Private and government (NOAA) forecasters in New York and Boston are under siege for overestimating Monday night’s snowfall amounts. In their defense even the ECMWF (European) model busted. Total amounts ranged from 8 inches at Central Park to 21 at Sayville, Long Island, only 50 miles due east. I’m not sure weather models will ever able to effectively pinpoint such extremes over such a small geographical area.

Weather isn’t an exact science, like economics or foreign policy.

Snowstorm’s Forecast Was Mostly Right, Even If It Felt Wrong In New York. Manhattan was on the western edge of the heaviest snow bands; 40 miles made the difference between 8″ and 21″. Here’s an excerpt from The New York Times: “…One of the difficulties with forecasting major storms, Dr. Sobel said, is that a small error in predicting the path of the storm can cause a much larger error in impact. “The bigger the event, the bigger the bust potential,” he said. In this storm, the predicted snowfall gradients — charts showing how much would accumulate where — were very steep. “So a little bit of track error means a big snowfall error,” he said...”

Photo credit above: “Snow swirls into the air as Ted Diamond operates a snow blower to clear out his driveway on Greenvale Drive in East Northport on Tuesday, Jan. 27, 2015, in New York. Long Island was one of several areas throughout the state to be hit by a blizzard overnight into this morning.” (AP Photo/Kathy Kmonicek).

Partly Wrong With A Chance of Being Right: Weather Forecast. Why do weather models fail? In light of the Big Bust out east I wanted to include a link to a storyy at ScienceDaily; here’s an excerpt: “…For example, they found that in the eastern Mediterranean, particles in the atmosphere were the most important cause of forecast fallacies, followed by land cover change. They also found topography to be the most influential factor affecting weather around the world. “The only tool the weather forecaster has is his model, and the only choice he or she has is to look at different models, each of which has strengths and weaknesses,” said Prof. Alpert…”

What Exactly Is A Nor’easter? Newsweek has a good description; here’s an excerpt: “…A classic nor’easter results when an existing low-pressure system moves across the country from west to east and then spawns a new storm off the East Coast, usually between the Carolinas and New Jersey, explains Keith Seitter, executive director of the American Meteorological Society. The initial storm may not have produced a huge amount of precipitation as it moved over land, but the new storm goes through an “explosive development,” says Seitter, and becomes a “monster storm” that absorbs the original one…”

Image credit above: “A winter storm approaches the eastern United States in a satellite image released January 26, 2015. The National Weather Service has issued a blizzard warning for New York City and surrounding areas between coastal New Jersey and Connecticut, beginning 1 p.m. EST on Monday. The storm will worsen overnight into Tuesday morning.” NOAA/Reuters.

Snow Scary. The New Yorker has a terrific article that helps to explain why the USA is a nation of extreme-weather junkies; here’s a clip: “…Edgework” is precisely what extreme weather is. A winter storm—or any storm, really—approximates this thrill. It’s powerful, and even dangerous. But safely ensconced inside, and in front of our computer screens, we don’t think that it will really hurt us. The power might go out, but then we would be able to share a picture of a car buried in a snowdrift. And then, soon, it will be over. You will have had the thrill, and you might have gained control over it by capturing a moment of “danger,” but, in all, it seems a relatively minor risk. We satisfy our inner risk-seeker without going into dangerous territory…”

7 Chilling Stories Of Snow Storms Throughout American History. TIME Magazine takes a numbing walk down memory lane; here’s a clip: “…It was Jan. 31, 1977, when this poor freezing man appeared on the cover of TIME. The story inside, which detailed the effects on the United States of what the publisher’s letter called “the bitterest cold spell in memory.” The first-ever reported snow fall in West Palm Beat, Fla., had shocked residents. Buffalo had been buried under more than 120 in. of the white stuff that season. And, ironically, areas that needed snow — the ski resorts of Idaho, for example — had to rely on snow-making machines despite the cold temperatures

Aeris iOS SDK
Aeris iOS Weather Framework: 2.0 Preview – Part 1

Our Aeris iOS Weather Framework has been in the hands of developers and Aeris users for about two and a half years already and has received a lot of positive feedback from everyone who has been using it within their own iOS applications. Our goal with the iOS framework has always been to make interacting and integrating with our core Aeris API quick and painless so you can focus your time on building great applications instead of worrying about fetching, parsing and displaying weather data. Now, after months of planning and development behind the scenes, we’re excited to give our first public preview of what the new 2.0 version of our iOS weather framework will bring! Instead of trying to build new features on top of old legacy code, we decided to start from scratch using modernized Objective-C code, new Objective-C literals and new iOS APIs with a huge number of improvements. As a result, we went straight to 2.0 with a complete rewrite, so let’s preview some of the major changes and improvements.
