Looks good @ericboucher, thanks. A couple of small things:

1. The create alert button is not readable both when it's inactive and active
2. Minor / nitpicking - there's a discrepancy in the UI between analysis and alerts selection of a hazard layer

Can't read text on the button:

Alerts vs analysis selection of hazard layer

If I try to create an alert without above / below parameters, I correctly get the message to add them. After adding them, the create alert button never becomes active again blocking me from creating the alert.
