East Devon District Council (EDDC) is working from lunchtime today (November 13) to draft in concrete barriers to protect the seawall from the next storm due to hit on Wednesday.
A spokesman for EDDC said: "More concrete blocks will be placed around Exmouth’s seawall, and an excavator and a bulldozer will be used to move sand over the base of the wall. These steps are being taken due to the stormy weather forecast for Wednesday.
"A longer-term solution is planned for later this winter."
The Met Office has issued a yellow weather warning running from 5am to midday.
It covers most of the South West across to the South East.
A Met Office spokesperson said: "A band of squally, thundery rain is likely to push quickly east across the warning area through Tuesday morning."
The last storm, Ciaran, caused widespread destruction when it hit Devon a few weeks ago, a few days before the storm, EDDC contractors spotted cracks in the wall and rushed to install temporary barriers around the wall to protect it.
