Travel warning: Tropical Storm Beryl hits Caribbean islands as state of emergency declared

As of Sunday morning, Beryl was moving at 20mph with winds of 45mph.

It is expected to hit the south of Puerto Rico later today with possible 60mph winds.

Dr Joel Myers, founder, president and chairman of AccuWeather explained: “Any heavy rainfall is capable of causing flash flooding.

“This is particularly true in the places that get heavy downpours, especially low-lying and poor drainage areas.

“Heavy rain, of course, can always trigger dangerous mudslides.”
