 Despite the storm's interaction with land, radar imagery showed a ragged eye-like feature, and Doppler weather radar data indicated wind speeds in excess of hurricane force.Just after its initial landfall, Irene was accordingly upgraded to a Category 1 hurricane, the first of the 2011 Atlantic hurricane season.With the hurricane then situated just north of the mountainous coast of Hispaniola, the storm deepened little after reemerging over water, and any additional organization during the rest of the day was gradual.
