Hurricane Irma Strikes Florida | NASA Earth


After battering Cuba and several Caribbean islands for most of a week as it crept slowly northwestward, Hurricane Irma turned north into Florida on September 10, 2017. Heavy rain and hurricane-force winds battered both the east and west coasts of southern Florida, even though the eye of the monstrous storm made landfall in the southwestern part of the state. Seas were rising with storm surges as far north as Charleston, South Carolina.

Hurricane Irma made its first U.S. landfall on Cudjoe Key, Florida, about 30 miles east of Key West, around 9 a.m. on September 10. The storm was rated as a category 4, with sustained winds of 130 miles per hour at the time. It made its second landfall at Marco Island around 3:30 p.m. with similarly potent winds.

At 5 p.m. Eastern Daylight Time, the National Hurricane Center reported that Irma was over Naples, Florida, bringing sustained winds of 110 miles (180 kilometer) per hour, with gusts to 140 miles per hour. Hurricane-force winds extended 80 miles (130 kilometers) from the center of the storm; tropical storm winds stretched at least 220 miles (350 kilometers), wider than the state from west to east. The storm was moving north at 14 miles (22 kilometers) per hour. It was expected to hug the west coast of Florida through Monday morning.

Geostationary Operational Environmental Satellite 13 (GOES-13) acquired data for this composite image at 8:15 a.m. on September 10 as the storm was passing over the Florida Keys. Infrared data (band 4) is overlaid on a MODIS blue marble. The satellite is operated by the National Oceanic and Atmospheric Administration (NOAA), while NASA helps develop and launch the GOES series of satellites.

Though much popular interest focuses on the winds and rain of a hurricane, storm surges are often the most deadly part of such an event. National Weather Service (NWS) forecasters warned of dangerous storm surges from the Florida Keys to Tampa Bay. Forecasters predicted waters as high as 10 feet (3 meters) above normal in places. The western shore is known for its relatively shallow coastal waters, and many neighborhoods are carved into lagoons and canals near the shore. “This is a life-threatening situation,” NWS declared.

Irma has been churning at hurricane force since August 31, and it has been a major hurricane—category 3 or above—for nearly all of that time.

Major Solar Flare | NASA SDO


A large sunspot was the source of a powerful solar flare (an X 9.3) and a coronal mass ejection (Sept. 6, 2017). The flare was the largest solar flare of the last decade. For one thing, it created a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean. Sunspot 2673 has been also the source of several other smaller to medium-sized solar flares over the past few days. Data from the SOHO spacecraft shows the large cloud of particles blasting into space just after the flare.

Note: the bright vertical line and the other rays with barred lines are aberrations in our instruments caused by the bright flash of the flare.

Hurricane Irma at 11 a.m. EDT on Saturday, September 9, 2017

At 11 a.m. EDT (1500 UTC), the eye of Hurricane Irma was located by a reconnaissance plane and radar near latitude 22.8 North, longitude 79.8 West. Irma is moving toward the west along the north coast of Cuba at near 9 mph (15 km/h). A northwest motion is expected to begin later today with a turn toward the north-northwest on Sunday.

Maximum sustained winds are near 125 mph (205 km/h) with higher gusts. Irma is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Irma is forecast to re-strengthen once it moves away from Cuba, and Irma is expected to remain a powerful hurricane as it approaches Florida. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). The minimum central pressure reported by an Air Force plane was 941 millibars.

On the forecast track, the core of Irma will continue to move near or over the north coast of Cuba later today, and will reach the Florida Keys Sunday morning. The hurricane is expected to move along or near the southwest coast of Florida Sunday afternoon.

Hurricane Irma nears South Florida | NASA-NOAA GOES-16 Satellite


The NOAA-NASA satellite GOES-16 captured this geocolor image of Hurricane Irma passing the eastern end of Cuba at about 8:00 a.m. EDT on Sept. 8, 2017. Forecasters say the eye of Irma should move near the north coast of Cuba and the central Bahamas on Friday, Sept. 8 and Saturday, Sept. 9, and be near the Florida Keys and the southern Florida Peninsula Sunday morning. Irma, now a category 4 storm, has maximum sustained winds near 155 mph with higher gusts as of 2 p.m. EDT on Sept. 8. Some fluctuations in intensity are likely during the next day or two, but Irma is forecast to remain a powerful category 4 hurricane as it approaches Florida.

Created by NOAA's partners at the Cooperative Institute for Research in the Atmosphere, the experimental geocolor imagery enhancement shown here displays geostationary satellite data in different ways depending on whether it is day or night. This image, captured as daylight moves into the area, offers a blend of both, with nighttime features on the left side of the image and daytime on the right. In nighttime imagery, liquid water clouds appear in shades of blue, ice clouds are grayish-white, water looks black, and land appears gray. (The city lights are a static background created with VIIRS Day/Night Band imagery. It does not show any existing power outages.) In daytime imagery, land and shallow-water features appear as they do in true-color imagery.

Hurricane Irma over Cuba | NASA Earth


The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired a natural-color image of Irma (below) at 10:00 a.m. local time (16:00 Universal Time) on September 8, 2017.

The NASA Short-term Prediction Research and Transition Center remarked on the storm’s “buzzsaw appearance.” The National Weather Service field office in Miami warned of “large airborne projectiles” and cautioned that some locations may be “uninhabitable for weeks or months” after the storm. Eric Blake, a meteorologist with the National Hurricane Center, simply tweeted that he had “never seen anything like this in the modern record” and that the forecast made him “sick to his stomach.”

In some respects, Irma is an unusual and record-breaking storm. On September 8, the storm had generated more accumulated cyclone energy—a term meteorologists use to describe the destructive potential of a hurricane—than any other Atlantic storm on record, according to meteorologist Philip Klotzbach of Colorado State University. Irma also broke a record for generating the most accumulated cyclone energy in a 24-hour period.

“Our human assets and aircraft penetrations are critical but limited,” said Marshall Shepherd, an atmospheric scientist at the University of Georgia. “Satellites provide a unique perspective on clouds, rainfall, sea surface state, sea surface temperature, and more. Only the satellite vantage point can provide continuous coverage of all three storms without having to refuel or sleep.”

A Menacing Line of Hurricanes | NASA Earth



Meteorologists struggled to find the right words to describe the situation as a line of three hurricanes—two of them major and all of them threatening land—brewed in the Atlantic basin in September 2017.

Forecasters were most concerned about Irma, which was on track to make landfall in densely populated South Florida on September 10 as a large category 4 storm. Meanwhile, category 2 Hurricane Katia was headed for Mexico, where it was expected to make landfall on September 9. And just days after Irma devastated the Leeward Islands, the chain of small Caribbean islands braced for another blow—this time from category 4 Hurricane Jose.

The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured the data for a mosaic of Katia, Irma, and Jose as they appeared in the early hours of September 8, 2017. The images were acquired by the VIIRS “day-night band,” which detects light signals in a range of wavelengths from green to near-infrared, and uses filtering techniques to observe signals such as city lights, auroras, wildfires, and reflected moonlight. In this case, the clouds were lit by the nearly full Moon. The image is a composite, showing cloud imagery combined with data on city lights.

Three Hurricanes in the Atlantic | NASA Earth



There was no shortage of storms brewing across the Atlantic basin in September 2017. On September 6, hurricanes Katia, Irma, and Jose lined up across the basin. The trio is visible in this image, captured that day by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. The image is a mosaic, assembled from images acquired throughout the day during several orbits of the satellite.

On September 6, Katia had strengthened over the southwestern Gulf of Mexico and was upgraded from tropical storm to hurricane status. The eye of Irma, a raging category 5 storm, passed north of Puerto Rico but still delivered strong winds and rain the Caribbean island. Meanwhile, Jose spun in the central Atlantic Ocean, and was also upgraded that day from a tropical storm to hurricane.

The bright strips are reflected sunlight, or “glint,” which show up over ocean areas in the middle of each orbit.

NASA's Voyager 1 Launches Aboard Titan III/Centaur in 1977


The Voyager 1 aboard the Titan III/Centaur lifted off on September 5, 1977, joining its sister spacecraft, the Voyager 2. NASA's Voyager 1 spacecraft launched atop its Titan/Centaur-6 launch vehicle from the Kennedy Space Center Launch Complex in Florida on September 5, 1977, at 8:56 a.m. local time.

The twin Voyager 1 and 2 spacecraft are still operating and traveling where no spacecraft—or anything touched by humanity—has gone before. As we celebrate the 40th anniversary of the Voyager 1 launch, we reflect on the vision that inspired the mission, its greatest achievements, and its enduring legacy.
