Storm Isha is expected to bring very strong winds and some heavy rain across the UK, from Sunday, 21 January until the early afternoon of Monday, 22 January.

The Southern, Gatwick Express, Thameslink and Great Northern networks are subject to Yellow and Amber weather warnings.

Trains on some routes will be restricted to 50mph during the worst of the weather, which will lead to later arrivals on some journeys.

If any lines need to close at short notice due to the effects of the weather, some services may be cancelled or changed at short notice.

There aren't currently any service changes caused by the storm, but we will update this page with any developments. Please check back here before you begin your journey.

Can you tell me more about this?

Teams will be doing everything they can to keep trains moving, but we expect some disruption, and we'll keep you informed. You can also see weather advice from the Met Office here.

Strong winds cause a number of issues for the railway. Routes are lined by huge numbers of trees, and although these are regularly assessed, even one tree can cause significant disruption when it falls onto the track. Specialist teams will need to attend and make sure it is removed, and that any other nearby trees have not been affected.

There may also be debris being blown onto the line, often from surrounding properties. We encourage all our neighbours to make sure their property is safe and secure, so that it doesn't end up on the track, where it's likely to be damaged. Again, in these cases, staff will attend and make sure the railway is clear.

Speed restrictions will be put in place to allow drivers to stop in time, should there be obstructions on the railway. On routes with overhead wires, these may also be affected by high wind speeds. Your journey may be delayed, as this means the network has lower capacity, because trains take longer to travel along each section of track.
