WINTHROP, Mass. (WHDH) -- Residents in coastal towns like Winthrop that decide to stay have been told to stay inside and off the roads. Flooding is expected and as the winds pick up, downed trees and power lines are also expected.

By early Monday morning the winds were 25-miles-per-hour. The geographical challenge of Winthrop is the way the town is located with water on all sides, which makes water the town’s biggest concern.

High tide was expected to be around 11:30 in the morning. Eighteen hours of winds were expected to push that water up over the sea wall.

There is a neighborhood that butts up against the sea wall where the flood risk is high. Residents know that when the storms come in there is a real possibility of flooding.

One of the things the town has done to prepare in Winthrop was to create a list of homes that already contacted the city, requesting assistance in case the basements flood so they know which homes they need to go to pump the basements out.

Residents have been told not to go into the basement for fear of electrocution.

Residents were asked to leave by 9 a.m. Monday morning and those that decide to stay have been asked to remain indoors and off the roads for safety reasons.

The winds were at 43 miles per hour as of 6:30 a.m. Monday. Water is expected to come up over the sea wall.
