I work as a journalist here in Italy and some officials during the day already discussed in public the high chance of a regional lockdown. Then, the document was leaked by local institutions. But everything was quite obvious since this morning, apart from some areas outside Lombardia that are going to be considered "red" (like Pesaro, where the numbers are climbing up and they probably want to avoid a situation similar to Bergamo or Lodi).
Fellow italian journo here, i can confirm all of this. The draft has been making the rounds in ANSA agency since last night.
Today at the Protezione Civile press conference some collegues started pressing, at this point it was obvious they had to say something today due to the amount of discussion regarding said measures.
