north-central Gulf of Mexico, and although the winds may not be overly strong (75 miles per hour is still nothing to laugh at), the system is expected to provide a plethora of potential weather hazards to several areas from the Gulf Coast to the Southeast States. Continuing on a northwest heading, the storm is expected to slow down before making landfall in Louisiana on Wednesday.  The slow moving nature of the tropical system will provide a threat for unusually high amounts of rain, which is concerning considering the fact that tropical systems produce very heavy rain amounts as it is.  Heavy rain, resulting flooding, high winds, storm surge, and beach erosion all top the list of potential hazards with the additional threat of isolated tornadoes (see the latest Tornado Watch from the Storm Prediction Center).
