Purple and unwelcome (but thriving)

Despite the dry conditions this summer in the Mid-Atlantic, it looks to me like this is a good year for purple loosestrife in New Jersey.  The thin vertical stems are thriving in low areas and I even saw some in open fields.  Is the state less vigilant this year?  In past years, I'd see a patch of purple loosestrife one week, and the next week it would be gone.  Last week I saw this patch near the intersection of Route 12 and County Road 579, but couldn't stop. I remembered it this week.
