Aleutian Low Aaron is the first storm of the 2011 Aleutian Low Season. It became a Category 2 storm. It formed on September 14 as a Category 1. It continued to strengthen until it peaked at 988mb, still a Category 1. It then weakened into an ex-low on September 16. Then after entering water again, it became a Category 1 on September 18. After rapid strengthening, it became a Category 2 and peaked at 980mb. On September 19, a day after Aaron reformed, the system dissipated.

After its extensive damage, many councils have requested to the KWS for the name to be retired.

Meteorological History

Aaron formed out of a tropical wave that moved from Africa. The wave formed on September 2, 2011 and crossed the Atlantic with no development at all. It had to pass Hurricane Katia in the Atlantic, which was a strong Category 4 (Saffir-Simpson Hurricane Scale), on the way into the Caribbean. After entering the Caribbean it still had no development even though there were waters of 30°C/86°F, if it did develop, it would have become Ophelia. After battling with Katia, it then had to battle with Tropical Storm Nate, but the wave moved north westwards towards the US border. As the wave made landfall, most of its cloud dissipated. Just 1 day later, it re-entered sea and then made a little more development. It passed through the Pacific Hurricane basin into the Alaska Low basin. And the pressure was low enough to become a named low, making it the first storm of the season. It began as a Category 1 in the Bering Strait, and due to high pressure moving from the north, Aaron moved southwards. It then made a turn to the east then North East. After making landfall in the Alaska Interior, it quickly weakened into an ex-low. It moved north-west until it reached sea again and then it redeveloped. Even

though it was a new developed system, later found out it wasn't, the Alaska Windstorm Center did not give the system a new name. The system was a Depression, and quickly became a Category 1 again. Just hours later, it became the seasons first Category 2 low, and then made landfall on the Alaska Peninsula. Aaron then moved into the Gulf of Alaska and weakened to a Subtropical Depression. It then became an ex-low on September 19 just 300 miles W of the Alaska Panhandle. The storm then turned into a Pacific Northwest cyclone, and impacted the West Coast of the USA. The storm dissipated over the Colorado Rockies.
