Tropical Storm Karen formed this morning in the SE Gulf of Mexico. The National Hurricane Center provides excellent satellite images and animated loops, which are updated regularly. The image above is an infrared image, which essentially shows temperatures across the Gulf of Mexico region. Colder temperatures indicate higher cloud tops and more enhanced convection. This image shows some impressive outflow (see the white cirrus clouds on perimeter of cloud deck), which may be one reason why Karen is strengthening so rapidly.
The National Hurricane Center forecasts Karen to track into the central Gulf of Mexico, then eventually make a turn to the north and northeast. The center of circulation should approach the northern Gulf Coast over the weekend.
