Valdez-Based Crowley Tug Alert Brings Kulluk Back Under Tow

Crowley tug Alert on Prince William Sound
According to the Unified Command Joint Information Center in Anchorage's Frontier Building:
The Kulluk drilling vessel is under tow by the Aiviq and tug Alert. All three vessels are currently located about 19 miles southeast of Kodiak Island.  
At approximately 12:45 a.m., Monday, Dec. 31, the Alert was able to secure the 400-foot line that was previously the tow line used by the Aiviq. The Alert successfully added tension to the line to test its ability to hold.  
Later in the morning, the Aiviq also restored its connection to the Kulluk. Ensuring the safety of personnel and protecting the area's environment continue to be of the utmost importance. Difficult weather conditions are anticipated to continue over the next several days.  
Unified Command is evaluating all potential options to further secure the vessel until the weather clears.
Among other things, the Unified Command has asked for mobilization of a team from International Bird Rescue:
International Bird Rescue’s senior wildlife response team has been activated as a contingency measure after a tow pulling the drilling vessel Kullak stalled Thursday in stormy seas near Alaska’s Kodiak Island, prompting an evacuation of its 18-person crew. 
Here's the current weather pattern analysis for the Gulf of Alaska:


It seems difficult to predict how serious Tuesday's storm might be, but the low pressure system right over the emergency area looks formidable.  Here's the current NOAA marine forecast for Kodiak waters:
