GOES-13's

13 satellite may be stationed in orbit over the eastern U.S., but it has a wide field of view from the eastern Atlantic to the eastern Pacific, and today it captured three tropical cyclones in one image. At 1445 UTC (10:45 a.m. EDT) today, Sept. 22, the Geostationary Operational Environmental Satellite called GOES-13 captured Tropical Storm Lisa in the far eastern Atlantic, a developing tropical low in the south-central Caribbean Sea, and Tropical Storm Georgette in the eastern Pacific Ocean, making landfall in Baja California. The GOES series of satellites are managed by NOAA, and NASA’s GOES Project at NASA’s Goddard Space Flight Center in Greenbelt, Md. creates images and animations from the satellite data.

Tropical Storm Lisa is struggling today in the eastern Atlantic Ocean because of wind shear and dry air. Lisa was producing a small area of deep convection near the surface of her center of her circulation. The center of circulation is also exposed to outside winds, which make the storm prime for weakening. In addition, there is a lot of dry air around Lisa at the middle levels of the troposphere (likely from the Saharan dust that has been blowing off the African coast). All of those things are indicators why Lisa has not been able to intensify.
