PHOENIX -- A severe monsoon storm left thousands in metropolitan Phoenix without power Sunday morning.
Some residents woke up to find Saturday night's storm had left a trail of uprooted trees and down utility poles.
Utility officials said more than 33,000 people across Phoenix had no electricity.
Arizona Public Service said 23,000 of their customers lost power -- many being in north Phoenix.
APS spokesman Steven Gotfried said that 2,600 customers were still without power Sunday afternoon and it was unknown when power would return.
Salt River Project said nearly 10,000 households initially lost power late Saturday.
SRP spokesman Scott Harelson said fewer than 100 customers were still waiting but would likely have power back by mid-day.
Harelson said most of the outages were relegated to eastern suburbs including Mesa, Apache Junction and Queen Creek.
Saturday's monsoon storm follows up thunderstorms and a "haboob" that hit metro Phoenix an evening prior. Photos of Friday's storms are seen below.
