NASA Satellites Show Hurricane Florence Strengthening

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA satellites are providing a lot of different kinds of data to forecasters at the National Hurricane Center to help them understand what’s happening Hurricane Florence. NASA’s Aqua satellite is providing visible, infrared and microwave imagery while the GPM core satellite is providing additional data like rain rates throughout the storm and cloud heights.

Last Friday, September 7th, Florence was a sheared tropical storm but on Saturday vertical shear lessened and Florence started to get better organized. Today, September 10th Hurricane Florence was rapidly strengthening and became a major hurricane.

At 12:55am CDT (0555 UTC) on September 10th, the MODIS instrument aboard NASA’s Aqua satellite looked at Hurricane Florence in infrared light. MODIS found coldest cloud tops (red) had temperatures near minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius) in the northern and western eyewall. (NASA/NRL)

Written by Stephen Lang / Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – On Sunday April 15th, 2018 a line of strong storms at one point stretched from the Florida Straits below the Florida Keys all the way up the East Coast and into Ohio. The Global Precipitation Measurement mission or GPM core satellite analyzed the severe storms as it passed overhead. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.

Many of the storms were strong with wide spread reports of wind damage from north Florida up through the Carolinas and into central Virginia.

GPM captured an image of the advancing line of storms on April 16 at 00:17 UTC (8:17 pm EDT, April 15). GPM showed a narrow leading line of thunderstorms producing heavy rain rates (orange and red areas), followed by a much broader area of light to moderate rain (blue and lighter green areas).

NASA monitors Midwest Precipitation and Flooding

 

Written by Harold F. Pierce/Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Much of the U.S. Midwest has received above normal precipitation this winter. A NASA rainfall analysis provided a look at the precipitation that contributed to current flooding.

Recent heavy rainfall and melting snow has caused flooding from eastern Texas to Michigan. Major flooding is expected along the Ohio River in Illinois and Kentucky.

On February 23rd, the National Weather Service noted that several locations along the Ohio River near Louisville were under flood warnings. Parts of Arkansas and Indiana are also preparing for major flooding.

Data collected from December 21, 2017 to February 23, 2018 in this NASA TMPA rainfall anomaly analysis indicated that parts of the upper Midwest have had 5 mm (0.2 inches) of precipitation per day above normal so far this winter. (NASA/Hal Pierce)

NASA and NOAA Satellites observe Hurricane Nate make Landfall

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP satellite analyzed the temperatures in Hurricane Nate’s cloud tops and determined that the most powerful thunderstorms and heaviest rain areas were around the center of the tropical cyclone after it made landfall near the mouth of the Mississippi River.

At 8:00pm EDT/7:00pm CDT on October 7th, 2017 Hurricane Nate’s eye was at the mouth of the Mississippi River. National Weather Service radar data and surface observations indicated that Hurricane Nate made landfall near Biloxi, Mississippi, around 12:30am CDT/1:30am EDT on October 8th, with maximum winds of 85 mph (140 kph).

On October 8th at 4:20am EDT (0820 UTC) the MODIS instrument aboard NASA's Aqua satellite analyzed Nate's cloud top temperatures in infrared light and found strongest storms (yellow) around the center of circulation. (NASA/NRL)

NASA and NOAA Satellites capture images of Hurricane Irma hitting Florida

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – As Hurricane Irma approached southern Florida, a NASA satellite captured a night-time image of the storm in the Florida Straits and identified where the strongest storms were occurring within Irma’s structure. NOAA’s GOES satellite provided a visible image at the time of Irma’s landfall in the Florida Keys.

As Irma moved along the coast of Cuba, the storm weakened to a Category 3 Hurricane on the Saffir-Simpson Hurricane Wind Scale.

After moving away from the northern coast of Cuba, Irma passed over waters that are warmer than 30 degrees Celsius (86 degrees Fahrenheit).

This visible image of Category 4 Hurricane Irma was taken on Sunday Sept. 10, 2017 at 9:25 a.m. EDT (1325 UTC) by the NOAA GOES East satellite as its eye approached the southwestern coast of Florida. Hurricane Jose is seen (right) near the Leeward Islands. (NASA/NOAA GOES Project)
