The remnants of former hurricane Ida are forecast to move across the Wilton area Thursday morning, bringing a six-hour period of moderate-to-heavy rain.
Wilton’s director of emergency operations, Police Chief John Lynch, said that he does not expect any significant issues but town officials will be monitoring the situation through the end of the week.
The CT Department of Emergency Services and Public Protection has provided a detailed forecast based on the current models:
