During the peak of the rain storm in NJ+NY (see flooding deaths referenced
in previous email), the wireless emergency alert systems were sending,
simultaneously:

1) TORNADO WARNING SEEK SHELTER NOW GO TO BASEMENT [1]

2) FLOOD WARNING SEEK HIGH GROUND GET OUT OF BASEMENTS [2]

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.

the message itself)
