Hounslow Highways and Carillion, the council's contractors for streets and parks, between them handled 38 urgent call-outs as heavy winds battered the borough on Easter Monday (March 28) morning.
Those emergencies included 20 trees which had toppled onto or near public roads, half of which were from private properties.
Hounslow Highways was also called to 13 other potential safety hazards, including damaged walls, tiles and precariously hanging branches, all of which were made safe ahead of further inspection and repairs.
Hounslow Council said it had planned ahead for the storm, helping to ensure all roads were re-opened by midday on Monday.
As well as having staff on standby to deal with any damage on the day, it said tree inspections and pruning had been brought forward to ensure they could better withstand the gales.
Firefighters also had a busy morning on Monday, with London Fire Brigade saying it dealt with 110 storm-related incidents .
A number of attractions were closed to the public on Monday as a safety precaution , including Kew Gardens and Chiswick House and Gardens.
Runners in the Hillingdon Half Marathon also had cause for complaint as diversions due to storm damage added 0.1 miles to the route.
And Storm Katie wasn't finished there. On Wednesday morning, those on board a bus had a shock as a tree fell and smashed through the windscreen .
