Hurricanes have a life cycle, moving from tropical storm to full-on hurricane.

NASA's Aqua satellite caught Hurricane Florence developing an eye Sunday as the storm ramped up its intensity.

NASA's infrared data shows the strengthening eye in angry red, glaring from the center of the image.

Residents of the US East Coast are preparing for the storm's arrival as the National Weather Service warned on Monday that "Florence is forecast to bring devastating rainfall and flooding from the coast to the Appalachians."

The Aqua satellite measured the temperature of the cloud tops and found they reached a chilly minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius).

"NASA research has found that cloud top temperatures that cold have the capability to generate heavy rainfall," the space agency says.

The powerful thunderstorms that that left a path of destruction and at least 3 dead across the Northeast on Tuesday were so strong they generated a small tsunami off the coast, according to forecasters.

The National Weather Service said the weather-generated tsunami, known as a meteotsnuami, resulted in fluctuating water levels for several hours and was picked up on buoys off stretching from New Jersey up to southern New England.

"This kind of tsunami is generated by abrupt changes of atmospheric pressure in the causative storm system, which is a line of thunderstorms that moved over the ocean in this case," the NWS said.

"The combination of the air pressure effect on the ocean surface, and the speed at which the pressure disturbance travels, can generate abnormal waves in certain situations."

Data from buoys off the coast showed small fluctuations in water levels after 8 p.m., which lasted for several hours.

Most meteotsunamis are too small to notice, with water levels fluctuating by several inches or a foot above the normal tide, according to the weather agency.

On Wednesday, a tornado described by the National Weather Service as large and extremely dangerous tore through central Indiana, overturning cars and leveling a Starbucks store, Weather.com reports.

Miraculously, no injuries have been reported.

The tornado s destruction was widely documented on social media.

One video, provided to WTHR-TV by witness Brandon Mobley, appears to show the moment the Starbucks in Kokomo, Indiana, collapsed.

We want to express our heartfelt concern for all those personally affected by a tornado that touched down in the community Kokomo, Indiana, this afternoon, said the coffee company in a statement.

We are relieved to report all partners employees and customers from the Starbucks store at US 35 & SR 22 are safe.

As a student and observer of meteorology, it constantly bums me out that people do not understand what it means when someone says there s an X% chance of rain tomorrow.

A 50 percent chance of rain does not mean there s a 1-in-2 chance that you re going to get wet.

The terminology most used by people is There s a 80 percent chance of rain, which reasonably leads people to think there s an 80 percent chance it s going to rain on them.

And when they don t see it, they think their local meteorologists are huffing glue.

To quote the National Weather Service NWS , what PoP is actually describing is the chance of rain at any point over an area.

PoP C x A where C the confidence that precipitation will occur somewhere in the forecast area, and where A the percent of the area that will receive measurable precipitation, if it occurs at all.

When you curse the weatherman for wrongly predicting an afternoon of clear skies, take pity.

Forecasting is hard: It s subject to tons of variables, conditions are constantly changing, and everything affects everything else.

But soon the whims of the weather gods will seem a little less arbitrary: The agency that runs the National Weather Service is working on making its predictions much, much better.

In the past couple of years, the National Oceanic and Atmospheric Administration has been planning a push to overhaul the National Weather Service s quarter-century-old system.

And that would change everything from event planning to giving people enough time to evacuate areas before they re blasted by the elements.

But not everyone s happy about the model NOAA picked, an in-house solution called FV3 for Finite-Volume on a Cubed-Sphere .

Strong winds can blow down tree branches, move garbage cans across the street, and in true Wizard of Oz style, even blow away your little dog, too.

On Tuesday, the National Weather Service in Cleveland, Ohio, added a special warning to its weather advisory.

"Hold on to your pooch!"

the Cleveland NWS said in a tweet announcing that it had put an unofficial "small dog warning" wind advisory into effect for northern Ohio and Northwest Pennsylvania through Wednesday evening due to wind gusts up to 50 mph.

The National Weather Service in Cleveland didn't immediately respond to a request for comment, but Twitter users were paw-sitively entertained, tweeting GIFs of startled dogs and referencing Toto from The Wizard of Oz.

The dog warning isn't that far-fetched.

Snowfall rates are picking up for the storm hitting the Northeast.

The National Weather Service said there might be thundersnow: a rare meteorological phenomenon in which a storm involving thunder and lightning also drops snow.

Not long after noon, it happened.

That's rare because the types of storms that drop snow and the types of storms that cause thunder and lightning are usually very different.

The second nor'easter to strike in March is dropping snow and rain throughout the East Coast.

The New York office of the National Weather Service (NWS) announced Wednesday morning that the region might see thundersnow later in the day.

A runner spotted a “fire rainbow” over Pinnacles National Park in California, the National Weather Service, Bay Area announced on Wednesday.

A fire rainbow, more formally known as a circumhorizontal arc, occurs when the sun is more than 58 degrees above the horizon.

The sun must be higher than this in order for the arc to form, according to Atmospheric Optics.

Then, as the sun’s light is refracted off of the ice crystals in cirrus clouds, “you get pretty colors,” Roger Gass, a meteorologist with the National Weather Service (NWS), told SFGate.

"It's an optical illusion,” he added.

If you live in North America, you have a good chance of seeing the phenomena, especially during the summer months.

The message in Mandarin Chinese was part of an ongoing robocall campaign hitting phones around the country

A National Weather Service in the US state of Maryland has been hit by a robocall campaign that resulted in a scam message in Mandarin Chinese being broadcast over the building’s intercom system.

The message, in a recorded woman’s voice, played itself over the building’s loudspeakers on Wednesday morning.

It is part of an ongoing robocall scam campaign aimed at Chinese speakers, which also reached telephones at the same location, the US National Oceanic and Atmospheric Administration’s (NOAA) Centre for Weather and Climate Prediction in College Park, Maryland.

An email message from a branch IT manager said the phone system involved was not linked to any of the buiding’s government IT systems, according to the Washington Post.

The email said it wasn’t clear how the robocall system accessed the building’s intercom.

On Oct. 24, the National Weather Service or NWS in Tiyan, Guam issued the warning that "Catastrophic winds for Tinian and Saipan are imminent" as the eye of Super typhoon Yutu neared both islands.

NASA-JAXA's GPM satellite and NOAA's NOAA-20 satellite provided a look at the heavy rainfall and the structure and eye of the storm.

Maximum sustained winds in the eye wall are 180 mph or stronger making Yutu a dangerous category 5 super typhoon.

At 10:22 a.m. EDT (1422 UTC) on Oct. 24 or 12:22 a.m. CHST (local time) on Thursday, Oct. 25, the NWS noted "Typhoon warnings remain in effect for Rota, Tinian and Saipan.

The winds will be much stronger than in Typhoon Soudelor!"

Tropical storm conditions are expected at Alamagan, Pagan, and Agrihan around midnight tonight through late Thursday evening (CHST time).
