The future of Calderdale and Huddersfield A&E units will be revealed in public for the first time on Tuesday.
Fears that Halifax would lose its A&E unit have been circulating since last November.
Last week MPs and top councillors were given private briefings on NHS plans for emergency care at Calderdale Royal Hospital and Huddersfield Royal Infirmary.
It is thought officials favour closing the Halifax unit and focussing resources at HRI due to Kirklees’ larger population and Huddersfield’s more central location.
Speculation that Calderdale was more likely to close than Huddersfield has been growing since the autumn after Halifax MP, Linda Riordan said she had been unable to get assurances that CRH A&E was staying open.
Mrs Riordan said the closure of the town’s emergency unit “would be a tragedy for both communities”.
She added: “We’ve got a population from Todmorden to the other side of Holmfirth – I don’t think one A&E can cope with that.”
In December, Public Health minister Jane Ellison confirmed the Calderdale and Huddersfield NHS hospital trust was looking to “co-locate” some of its services but no official announcements have been made since.
The first public airing of the plans will be at a Kirklees Council Health and Wellbeing Board at 2pm at Huddersfield Town Hall.
