NEW ORLEANS [-8/31/05]-- According to Dominican sources, there are no reports of injuries among the Dominicans who reside in New Orleans in the aftermath of Hurricane Katrina. However, the status of eight friars at St. Anthony Priory is still unknown.Many of the 30 Dominican brothers who live in New Orleans have either been evacuated or are accounted for, including the provincial, Marty Gleason, OP and Chrys Finn, OP, who stayed at St. Dominic Priory and were rescued by boat.

There are still a number of Eucharistic Missionaries (EMD) sisters stranded in New Orleans and the Columbus Dominicans are working with the Kentucky Sisters to find a way to get them out. Although neither the EMDs nor St Mary's Dominicans have been able to assess their losses or damages, the prospects look disasterous in light of the worst natural disaster in US history.

Someone on Phatmass.com reported that the nuns at the Lockport Monastery are OK and didn't get hit too badly. They only lost a few shingles! Deo Gratias!
