FL Gov. Rick Scott confirmed Saturday that 25,000 Florida residents are without power.
Scott called Irma a "catastrophic storm this state has never seen." The storm surge could get up to 15 feet above ground level.
Florida is calling for 10,000 volunteer nurses to assist in special needs shelters.
From the National Hurricane Center: "Irma is expected to make landfall in Florida as an extremely dangerous major hurricane, and will bring life-threatening wind impacts to much of the state regardless of the exact track of the center."
Scott urged residents last night: "If you have been ordered to evacuate, leave now. Not tonight, not in an hour, now." It is expected to hit the Florida Keys on Sunday morning, making its way through the state over the course of 30 hours.
Hurricane Jose in The Atlantic is a Category 4.
As of Friday morning, at least 20 people have died from Irma, per the NY Times, but the number is expected to rise as rescue efforts continue throughout the Caribbean.
Jupiter is home to the solar system's most powerful auroras. Their source is a mystery but researchers reported this week that they now know the planet's auroras are generated by processes different from those on Earth.
How it works on Earth: Auroras are created when the solar wind blows over the planet's magnetic fields and drives electrons into oxygen and nitrogen in the atmosphere. Those electrons then emit photons that the luckiest of us get to see as the vibrant colors of the Northern and Southern Lights.
How it works on Jupiter: It's different. The rotation of the planet in its own magnetic field, not the solar wind, can generate 400,000 volts of charge as it pushes electrons toward the atmosphere. But unlike on Earth, that doesn't create Jupiter's brightest auroras.
