GRACE MAKES LANDFALL ALONG THE EASTERN YUCATAN PENINSULA OF MEXICO NEAR TULUM

Satellite images and radar data from Belize indicate that Hurricane Grace made landfall along the eastern Yucatan Peninsula around 4:45 a.m. CDT just south of Tulum, Mexico.

A Weatherflow station at Xcaret Park near Playa del Carmen, Mexico, recently measured a sustained wind of 60 mph (97 km/h) and a gust to 85 mph (137 km/h). Another Weatherflow station located at Cancun, Mexico, recently measured a sustained wind of 59 mph (95 km/h) and a gust to 80 mph (129 km/h), while the Weatherflow site located at Puerto Morelos, Mexico, recently measured a sustained wind of 51 mph (83 km/h) a gust to 70 mph (113 km/h). On Cozumel, a sustained wind of 41 mph (66 km/h) and a gust to 68 mph (109 km/h) was observed at the Cozumel Lighthouse.

We are also watching a few tropical waves, either across the tropical Atlantic or emerging off the African coast this week, but development with these seems unlikely at this time.
