Today, you can follow the exploits of Jess in our Emergency Operations Centre on Twitter as she takes 999 calls. At the same time, she’ll be joined by colleagues from North West and East of England Ambulance Services. You can follow all three by following @OFFICIALWMAS or #team999 now. Between the three services we’ll take the best part of 9,000 calls during the day. Alternatively follow Jess and the others via the BBC Winter Watch facebook page https://www.facebook.com/events/1406296959631316/?ref=22. Here’s a short clip of Jess taking a 999 call with Press Officer Chris Kowalik tweeting beside her.
