GOES-13 Gets a "Full-Disk" Look at Weather in the Americas

(Click on image for larger view.)

The Earth is a dynamic "big blue marble" and NOAA's GOES-13 satellite captures "full-disk" images of it many times over each day. On October 25, 2011 there was a lot of activity happening in North and South America from Hurricane Rina in the Caribbean to powerful frontal systems.

This full disk visible image was taken from the Geostationary Operational Environmental Satellite, GOES-13 at 1745 UTC (1:45 p.m. EDT). NOAA manages the GOES-13 satellite, but the NASA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. created the image.

In the northern hemisphere the biggest weather story is Hurricane Rina, seen in the western Caribbean Sea. Hurricane Rina is a Category two hurricane on the Saffir-Simpson scale and is expected to strengthen further before making landfall in Mexico's Yucatan Peninsula. To the southeast of Rina is another tropical low pressure area that is trying to organize, but currently has a low chance of becoming a tropical depression.
Further north in the U.S. and Canada is a low pressure area situated over the province of Quebec. Clouds associated with the attached cold front are over the western Atlantic Ocean. Snow and rain are also falling over the Canadian provinces of Alberta, Saskatchewan and Manitoba today.

Meanwhile clouds associated with another low pressure area over eastern Nebraska and its warm front are bringing clouds and showers to the Ohio Valley today. On the western side of that low in the central U.S, the trailing cold front that links that low to another low pressure area over Colorado is bringing heavy snowfall to the Colorado Rockies.

In South America clouds associated with a low pressure system can be seen off the coasts of Argentina and Uruguay, in the southern Atlantic Ocean. Meanwhile, fair weather cumulus clouds populate the skies over Brazil. The Amazon River is also visible in Brazil between the cumulus clouds.
