Impact of the Storm  
As we sift through the information coming in from Mexico, key questions remain about the short and long-term effects of last week's storm:

  1. How many monarchs had already left?
  2. How low did temperatures fall — and for how long?
  3. How many of the remaining monarchs survived?
  4. What's the long-term effect on overwintering habitat?
