I hate to say this, but it seems that
$twcweather.alerts.length
will also count nulls. 
- OR -
I have had about 15 of these the past few days.
Each time, the weather was only slightly bad.
(not worthy of an alert, IMO)
On a clear day, it usually returns:

I have had 50-60 changes to my $twcweather.alerts.length,
but each time, $twcweather.alerts has been null…!!!
Would someone be willing to import the following piston to help me determine if this is normal?
If you don’t want the SMS, you can safely delete line 42, and the data will still be recorded in the log
So, I guess I’m capturing the wrong information for this thread. I’m only capturing the following two:
$twcweather.alerts[0].eventDescription
$twcweather.alerts[0].headlineText
I’m using them to announce through Echo Speaks and to send SMS messages using the following pistons (which is working perfectly now):
Gather information Piston:
Announcements Piston:
Every bit helps. You are under no obligation to capture the entire alert. The only reason I asked that originally is to gather data for all possible outcomes. (It has been calm in my location the past month) Without the contributions of everyone here, the wiki page would take MONTHS for me to put together…
Side Note:
You may want to use:
$twcweather.alerts.eventDescription
$twcweather.alerts.headlineText
without the zeros, since sometimes there is more than one alert currently active.
(with alerts, the 1 does not mean tomorrow. It means the second alert for right now)
For clarity, the responses after this double alert were:
In other words, if you were tracking:
$twcweather.alerts[0].eventDescription
you might not be alerted to the fog…
Edit:
It is very possible that I am describing:
$twcweather.alerts.eventDescription[0]
More testing is required…
@WCmore, I have not received a response from The Weather Company about providing a list of available weather warnings. I guess we are on our own.
Thanks for the update…
I suspect that TWC uses different weather sources in different countries. If my hunch is correct, then the results may not be standardized, and TWC would not have the answers we seek…
Of course, more testing is required…
Does this help

The Wiki has been updated.
Thanks for the new alert, “Civil Emergency Message”, which also included new data for significance and categories.
I believe the other two posts are all duplicate information.

When the length is greater than zero, are there any nulls? That piston is supposed to send the alert (or null) whenever the length is 1 or more.
Edit:
If you are using this piston from above, then any time the length is greater than zero, there should be extra information inside that SMS. Such as:
So I guess my question is, what is the extra information you see when length is 1 or more?
