Based on the current track, no interaction with land is expected.
According to weather forecasters, Hurricane Chris is expected to gain strength throughout Wednesday before weakening Thursday as it heads out to sea and away from USA coastal areas.
No coastal watches or warnings were in effect. As this happens, Chris will encounter cooler waters and weaken.
It looks like the UK's heatwave is set to come to an end as the remnants of a powerful hurricane swirling along the U.S. east coast is due to hit Britain.

The best course of action is to simply avoid the ocean on these unsafe days.

Hurricane Maria dealt a vicious blow when it hit Puerto Rico on September 20 with winds close to 150 miles per hour (240 kph), knocking out the island's already teetering electric grid and water supply. However, meteorologists do not expect it to make landfall in any part of U.S. Moving northeast and along, but not towards, the coast, the closest its projected path comes to land is Newfoundland, Canada.
Heavy rain of up to 100 mm in some areas could result in localized flooding, coupled with strong winds and storm surges with swells up to eight metres.
