Storm Gareth is forecast to bring gusts of up to 60mph with the Met Office issuing a severe weather warning lasting until mid-afternoon tomorrow (Wednesday 13 March).
The height of the storm looks likely to blast Brighton and Hove at about lunchtime today as the winds swirl from southwesterly to westerly and northwesterly.
The official forecaster warned of possible transport disruption, with a tree blown over on the Sunday as the storm limbered up.
The Met Office said: “Strong northwesterly winds are expected during Tuesday night and Wednesday with possible transport disruption.”
It said that some bus and train services may be affected, with some journeys taking longer.
And there were risks and could be delays for high-sided vehicles on exposed routes and bridges.
The Met Office also warned about the risk of some short term loss of power and other services, adding: “It’s likely that some coastal routes, seafronts and coastal communities are affected by spray and/or large waves.”
Drivers were urged to take care, make sensible choices and plan ahead.
The Met Office said: “Even moderate rain can reduce your ability to see and be seen. A good rule of thumb is ‘if it’s time for your wipers, it’s time to slow down’.
“If you can, choose main roads where you are less likely to be exposed to fallen branches and debris and flooding.
“Gusts of wind can unsettle vehicles – grip your steering wheel firmly with both hands. This is particularly important when planning to overtake.
“Keep an eye out for gaps between trees, buildings or bridges over a river or railway – these are some of the places you are more likely to be exposed to side winds.
“Ensure that you maintain enough room either side of your vehicle so you can account for it being blown sideways.
“Roads will be more slippery than usual in wet weather – be sure to give yourself more time to react when approaching a hazard.
“Increase your following gap to at least four seconds from the moving traffic in front.
“Keep your eyes peeled on the road at all times as spray from other vehicles can suddenly reduce your visibility.
“Remember it affects others too, so anticipate their actions and be prepared.
“Keep an eye out for cyclists, motorcyclists and pedestrians. Remember to give vulnerable road users including cyclists, motorcyclists and pedestrians more room than usual. They are more likely to be blown around by side winds – always keep a safe distance.
“During the storm, stay indoors as much as possible. If you do go out, try not to walk or shelter close to buildings and trees.
“Do not go outside to repair damage while the storm is in progress (and) do not drive unless your journey is really necessary.”
