National Weather Service alerts headed to smartphones

Live in an area prone to flash floods, hurricanes, blizzards? Smartphone users will soon get a severe-weather alert from the National Weather Service, a division of the National Oceanic and Atmospheric Administration.

The new nationwide emergency alert system, called the Wireless Emergency Alerts (WEA), sends 90-character text messages to smartphones of people facing extreme weather conditions. Severe weather defined by the NOAA includes tornadoes, flash floods, hurricanes, extreme wind, blizzards and ice storms, tsunamis, and dust storms. Note that thunderstorms aren't on the list because they occur so frequently. … Read more

How Navy supercomputers help sailors beat an ancient nemesis

MONTEREY, Calif.--One after another, the framed pictures on both walls of the narrow hallway tell the story: submarines and naval ships churning white wakes as they slash through open ocean, each photo accompanied by unbidden gratitude.

"Thank you for your team's efforts & hard work! You ensure my safety and enhance my tactical advantage," one reads.

Welcome to the U.S. Navy's Fleet Numerical Meteorology & Oceanography Center. That long-and-hard-to-say name notwithstanding, this is one of the United States military's sharpest weapons in the never-ending battle for survival in rough seas all around the … Read more

Dark Sky for iOS predicts the weather -- for the next 60 minutes

The App Store is home to lots of weather apps, most of which are good at forecasting the upcoming days and even hours. But few excel at telling you what the clouds might bring in the next hour.

That's where Dark Sky comes in. This new app, the product of a successful Kickstarter campaign, predicts the weather for your exact location for up to 60 minutes.

That could prove incredibly handy in a number of situations. For example, should you flee the beach in advance of those ominous-looking clouds? Nope, turns out they're going to blow right past; … Read more

Top weather apps for iOS

Whether you live in rainy Seattle or are expecting thunderstorms in Albany, N.Y., it's always a good idea to carry solid weather apps on your iPhone for quick forecasts.

The Weather Channel released version 5.0 of its app late last week with an upgraded interface and a few more features that will be useful to amateur meteorologists everywhere, but it doesn't have everything. One of the more useful parts of any local weather forecast is when you get to see the live Doppler radar for your location. The Weather Channel will show you a radar overlay, but you can't see it move. That's where the second app in this one-two punch comes in, NOAA Hi-Def Radar.

With this pair of apps, you might find that one or the other is the best weather app for you, but hopefully this comparison will help you find what best fits your needs.… Read more

The Weather Channel gets it right on iOS

The Weather Channel is a free weather-monitoring application that provides many more features than Apple's built-in Weather app. Released first in 2008, the app recently received a complete overhaul to the interface, adding features that make it even easier to check weather conditions wherever you are.

You can find paid weather applications that are more specialized, but The Weather Channel (sponsored by the cable channel of the same name) offers the features most people want in a weather app. You can view forecasts (hourly, 36-hour, and 10-day outlooks), quick access to Weather Channel local and regional video forecasts, severe … Read more

On the short list of must-haves for every iPhone owner: a good weather app. And the one that's bundled into iOS? Not so good.

If you ever checked out The Weather Channel for iOS and promptly turned your nose up at its cluttered, clunky interface, it's time for another look. The Weather Channel 5.0 for iPhone features a gorgeous new UI and some fun new sharing options.

Sharing? TWC has added a photo button to its Home screen; you can take a snapshot of the skies (or anything else) and share it via e-mail, Facebook, Twitter, or … Read more

Pinterest joins the billion-dollar network club

It's a good day for pinning photos, protecting privacy and paying your taxes:

Yet another social network joins the billionaires club. The social photo-sharing network Pinterest has been valued at $1.5 billion.

Pinterest makes no money, but you can bet that investors will push to change that by integrating e-commerce tools. And if you want to see what all the fuss is about, here are some tips and tricks to getting started on Pinterest.

'Monster sunspot' could bring solar flares

A group of sunspots 11 times wider than the Earth turned to face our planet, raising the possibility of solar flares and auroras tonight.

More than 60,000 miles wide, Sunspot Region 1476 became visible over the weekend and two coronal mass ejections (CMEs), where a portion of the sun's atmosphere breaks off, erupted on Tuesday.

The CMEs blasts could arrive on Earth later today and cause moderate geomagnetic storms later and auroras in the higher latitudes, according to NOAA's Space Weather Prediction Center.

The CMEs are traveling at 1.5 million miles per hour but, since they … Read more

Keep weather data handy with WeatherInfo

WeatherInfo is a simple application that keeps the current conditions and five-day forecast at your fingertips. It's not the most feature-packed weather app we've seen, but if you're looking for a program that can hang out unobtrusively in your system tray and provide you with weather info when you need it, it's not a bad choice.

The program's interface is straightforward and easy to navigate, with tabs dividing it into screens for Current, Forecast, and Options. The Current tab shows a thermometer with the current temperature down the left side, and a text box displays … Read more

Solar storm packs a weak punch so far

Space forecasters said today's solar storm is having relatively weak effects this morning, lessening the chances of disturbances to satellites or the grid. The event, however, is ongoing and still could cause problems.

A solar flare from an active spot on the sun Tuesday caused a coronal mass ejection (CME), where high-energy gases from the sun break off and hurtle off into space. This morning, this blast struck Earth in a storm which could last until tomorrow.

NOAA's Space Weather Prediction Center yesterday had forecast it to be a strong geomagnetic storm but so far it's been … Read more
