Entergy New Orleans no expects most power to be restored by September 8, 2021. Reminder, Puerto Rico is still experiencing rolling blackouts after 2017 hurricanes destroyed its power grid.


There were over 374 Wireless Emergency Alerts (WEA) issued nation-wide between August 26, 2021 (initial Hurricane warnings) and September 2, 2021. I'm still digging into how many WEA messages are related to Hurricane Ida (HUW event codes) versus other severe weather events elsewhere (e.g. FRW event codes - wildfire warnings in California).

Remember your Roku, Amazon Firestick, Google TV, etc. streaming devices don't alert you to emergency warnings. Amazon Alexa does have an option to activate severe weather warnings on its Echo/Echo Show devices.
