Hurricane Grace swept across the Yucatán Peninsula on Thursday, causing heavy rainfall, extensive power outages and mass evacuations, but without reaping either casualties or major property damage.

Degraded to tropical storms, Grace then moved into the Gulf of Mexico.

But there, Grace - who also created storms in Haiti and Jamaica - gained new strength and was upgraded to a hurricane again.

Requested to seek protection

"I want the people of the regions of Veracruz, Puebla, San Luis Potosi, Tamaulipas and Hidalgo to seek refuge in high-altitude places, with relatives or in storm shelters," Mexican President Andres Manuel Lopez wrote in a post on the social network Twitter.

According to the American National Hurricane Center (NHC), there may be heavy rainfall in the next few hours, but then Grace is expected to weaken as the storm moves in over the highlands inside Mexico.

In the video, you see, among other things, a US research flight from the agency NOAA, National Oceanic and Atmospheric Administration, which tracks Hurricane Grace off Mexico on 18 and 20 August.
