Even with the windows boarded up that building is not a safe place in a Cat 5 storm . That overhang on the roof is a major wind catcher . I would not want to have to shelter in there .
Josh Morgerman (@icyclone) spent a little time while scouting a safer location to observe the storm from explaining just that to those who were running the shelter.
He was in Perula Mexico last night but expects the town to be wiped out by the storm surge and winds.
