Happy #FullDiskFriday!
From NOAA Satellite and Information Service:
Happy #FullDiskFriday! As we head into the weekend, we want to take a moment to step back, 22,240 miles to be exact, and appreciate our amazing planet.
Each Friday we feature one of the many full disk Earth images captured by environmental satellites. This week, our image comes to us from the Japan Meteorological Agency's Himawari-8 satellite. This water vapor image, which was taken today, April 29, 2016, at 2:00pm EDT, shows the moisture content in the atmosphere over the entire Eastern Hemisphere. The bright and colored areas indicate high water vapor (moisture) content and/or ice crystals, while black and brown areas indicate little or no moisture present. Water vapor imagery is useful for both determining locations of moisture and atmospheric circulations.
The Himawari-8 satellite is the first unit of the Japan Meteorological Agency's third generation of geostationary satellites. The satellite provides visible light and infrared images of the Asia-Pacific region and its data are vital for global geostationary coverage. What's more, because it carries similar advanced imagers, Himawari-8 gives us a preview of what we can expect from NOAA's GOES-R satellite after it launches later this year.

What is a "SPENES" message and what does it look like?
From NOAA Satellite and Information Service:
What is a "SPENES" message and what does it look like?
The answer lies with the NOAA NESDIS's Satellite Analysis Branch (or SAB), which routinely provides analyses of satellite-derived weather data and trends to the National Weather Service's Weather Prediction Center (WPC) for use in the WPC's Mesoscale Precipitation Discussions (MPDs).
MPDs provides short-term guidance to National Weather Service forecast offices during heavy rain events that may lead to flash flooding. Ideally issued 1-6 hours ahead of time, MPDs consist of a graphic indicating the area of concern and any pertinent meteorological features, as well as a brief text discussion focused on the mesoscale features supporting the anticipated heavy rainfall.
In addition, the SAB provides satellite-based guidance messages, or SPENES, to the NWS Field Offices in Hawaii and Puerto Rico when heavy rains threaten those areas.
So, what does a SPENES message look like? Check out the links below for active messages or view older ones in the archives that date back to 2007.

Another Quiet Day in the Tropics!
From NASA's Hurricane Web Page:
Another Quiet Day in the Tropics!
Around the world, the tropics are quiet today, Friday, April 29, 2016. There are no areas suspect for tropical cyclone development. This view of the Atlantic and Eastern Pacific Oceans was created using images from NOAA's GOES-East satellite today.
