The wind speed hit 107mph in Scotland overnight and in other parts of the UK the Met Office said wind hit more than 70mph.
Martin Thomson, national operations manager for resilience at Transport Scotland, said, “Our resilience plans are in full effect.
“Staff from our trunk road operating companies are patrolling the network and undertaking inspections to respond quickly to any further tree fall or blocked drains.”
“Our roads operatives are out there on the network in these difficult conditions, doing all they can to respond to the worst impacts of Storm Isha.”
In Ireland around 230,000 properties are without power on Monday morning as Storm Isha caused disruption overnight.
Ireland’s Electricity Supply Board (ESB) said, “Fallen electricity wires are live and dangerous. Never approach or touch them. Call our emergency service immediately.”
The Tornado and Storm Research Organisation (TORRO) has warned on Monday that one or two tornadoes are “possible” in England in Wales.
The Met Office has issued a yellow weather warning as Storm Isha will bring strong winds in some areas.
TORRO said that wind speeds could reach 80mph and warned that there is a risk of “isolated tornadoes.”
TORRO said in a statement, “The cold front will move through overnight into Monday morning.
“The main upper forcing will be mostly to the north and northwest of the area, but some upper forcing will still be present, and a short-wave may cross the area overnight too.
“Additionally, one or two tornadoes are possible.”
