The rare tropical depression called "05A" in the Arabian Sea was hanging near the southern coast of Oman on Nov. 1 and 2, but forecasters expect it to fade over northeast Yemen over the weekend.

On Thursday, Nov. 1, O5A's clouds and fringe rains were affecting southern coastal Oman, from just south of the city of Duqm southwest to the border of Yemen.

By Nov. 2, 05A didn't move much as its center was still over the open waters of the Arabian Sea. It was located near 14.3 degrees north latitude and 57.2 east longitude, but it is headed to Yemen.

Maximum sustained winds were near 25 knots (28 mph) and gusts to 35 knots (40 mph). At that time it was 375 nautical miles east-northeast of Cape Guardafui, Somalia (pictured on the left as the peninsula jutting into the Arabian Sea), and moving westward at 8 knots (9 mph). The Joint Typhoon Warning Center expects 05A to make landfall and dissipate just south of Al Ghaydan, Yemen in the next day or two.

This infrared image from Nov. 1 at 1:30 p.m. local time was created by data from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite. Tropical Depression 05A's clouds are the blue and purple areas off the southern coast of Oman, stretching south to Yemen and west to the tip of Somalia. The blue areas show 05A's clouds and rains. This AIRS image shows the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the storm. The infrared signal does not penetrate through clouds. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth, revealing warmer temperatures (red).

Tropical Storms don't often form in the Arabian Sea, but this week, Tropical Storm "05A" has!

On Nov. 1 at 1500 UTC (11:00 a.m. EDT) what was a Tropical Storm on Oct. 29 and 30 is now Tropical Depression 05A. It was located 450 nautical miles east-northeast of Cape Guardafui, Somalia, at 14.7 degrees north latitude and 58.0 degrees east longitude. 05A has been moving west-northwest at 9 knots. Maximum sustained winds are now near 25 knots (29 mph) with gusts to 35 knots (40 mph).

NASA's Aqua Satellite Looks at 05A's Clouds

In this infrared image from Oct. 29 at 21:35 UTC (5:35 p.m. EDT), created by data from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite, 05a was a tropical storm with sustained winds of 40 knots (46 mph).

This AIRS image shows the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of Tropical Storm 05A. The infrared signal does not penetrate through clouds. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth, revealing warmer temperatures (red). This infrared image shows large areas of strong convection surrounding the core of the storm (in purple).
