Satellite image of Hurricane Grace taken at 1230Z:
Grace has re-acquired hurricane strength in the southwest Gulf of Mexico under a favorable upper atmospheric setup (low shear and outflow beneath vast upper ridging) and over warm waters… and is already measured by aircraft recon to have 85 mph maximum sustained winds. This special update is to acknowledge that the hurricane will likely make landfall as at least a top-end category 1 hurricane with 95 mph maximum sustained winds. If an organized core develops… rapid strengthening and category 2 strength cannot be ruled out. Interests in Veracruz should have finished preparing for Grace by now. If you like in or near the communities of Naranjos… Tuxpan… Tecolutla… and Nautla… be prepared to shelter indoors by tonight due to potentially damaging hurricane force winds stronger than previously forecast… and if you live at the coast be sure you have a plan ready to move further inland in the coming hours as the potential for a stronger coastal storm surge is increasing. The potential for some wind damage inland is increasing across northern Puebla due to the higher forecast landfall intensity… and the potential for gusty winds may spread as far west as Tlaxcala and eastern Hidalgo.
For more information on where Grace is expected to dump heavy rains and cause flood potential.. and also Henri who is also expected to impact parts of the northeast US… refer to full update #85 available on the home page of this site.
