* WHAT...For the Beach Hazards Statement, warm air temperatures in the 80s to near 90 may cause people to underestimate the dangers of the cold water temperatures in the upper 50s and lower 60s.. For the Coastal Flood Advisory, Minor coastal flooding is forecast. * WHERE...In Maine, Coastal York and Coastal Cumberland Counties.

For the Coastal Flood Advisory, from 9 PM this evening to 1 AM EDT Monday. * IMPACTS...Flooding of lots, parks, and roads with only isolated road closures expected. The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. When the water temperature is below 60 degrees, the average submerged person could lose dexterity within minutes and be unable to accomplish simple tasks. Anyone on boats or paddlecraft should use extreme caution to avoid this threat.
Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. A Beach Hazards Statement is issued on days when a significant number of boats and paddlecraft are expected to be out on the water and when warm air temperatures may cause people to underestimate the danger of the cold water. Paddle smart from the start. Always wear your life jacket. Be aware of wind conditions, tides, and localized currents. All boaters and paddlers are highly encouraged to contact the U.S. Coast Guard Auxiliary or U.S. Power Squadrons at https://cgaux.org/vsc/ to receive a FREE vessel check. This is a convenient, no consequence way to ensure your vessel is outfitted with all required safety equipment. Additionally, please label your paddlecraft with your contact information (IF FOUND Sticker) in the event it is found adrift on the water.
