The wider storm

An extratropical low developed off the tip of Kamchatka ahead of decaying Typhoon Lan. The extratropical low tapped into the energy associated with the typhoon and quickly strengthened from the upper 970 mb range to the mid 930's. This helped bring hurricane force winds to the Western and Central Aleutians.
