After Hurricane Grace passed the peninsula Yucaton in Mexico and the northern part of Belize, they will make a second landfall south of
Tampico at Friday night. Hurricane winds over 120 km/h and heavy precipitation are expected.
After Hurricane Grace brought intense rainfall to the Yucatan Peninsula and northern Belize, as well as wind gusts around 160 km/h and floodings, it weakened briefly as it made landfall, interrupting the energy supply. Thus, it was downgraded to a tropical cyclone yesterday (Thursday). However, a renewed intensification began over the southwestern Gulf of Mexico. This was due to very high water temperatures of 30°C and above and low to moderate wind shear values between 10 and 15 m/s. Furthermore, a very high moisture content exists. As a result, convection intensified and Grace again grew into a well-structured category 1 hurricane. The storm will likely continue to strengthen until landfall, making a second landfall Friday night as a Category 2 hurricane in Mexico. Then, a moderate storm surge, with winds up to 160 km/h, and heavy rains must be expected along the east coast. Accumulated precipitation amounts up to 300 mm are expected until Sunday. Therefore the greatest danger comes from intense rainfall, which will cause flooding and landslides, especially in mountainous and highly populated areas.
