Update: 1:35 a.m. EDT August 29, The eye seems to have stalled off the coast of Grande Isle, LA.  It seems to be doing a loop on radar and this will delay landfall.  Much of southeastern Louisiana will be pounded by high winds, heavy rains, and storm surge for much of Wednesday. The radar view from Slidell, LA at 1:05 a.m. EDT, August 29, 2012. --------------------------------------------------------------------------------------------------------- As Isaac makes landfall in southeastern Louisiana it is likely to be a category 1 hurricane.   This may not sound like much, but the winds are still a danger and shelter will be needed.   However, it is the water, both surge and rain, that are the biggest threat.   The storm is expected to slow down as it moves through southeastern Louisiana and could produce rain through Wednesday night.

Key West is normally a festive place particularly leading up to Labor Day.   Tonight it is a different place.   Webcams show only a few cars on the road on only a few brave souls on the streets.   Any partying is being done indoors.   It has been a rainy and windy day in Key West with gusts frequently up to 40 mph.   Peak gust occurred at 1:22 p.m. with winds to 47 mph.

Last night Isaac moved across Haiti dumping torrential rains on the poorest country in this hemisphere.   High winds and flooding rains pounded the country into the morning hours.   The center of Isaac moved across the southern mountains of Haiti, but then turned northward through the Windward Passage to reach the eastern tip of Cuba by midday.

This is the latest plot of the path of Isaac with the associated wind field.   Notice how erratic the path has been since moving into the Caribbean.   This is due to the complex weather pattern over the region playing a tug-of-war with the storm and it is still happening.

Tropical Storm Isaac did weaken some going over the mountains in Haiti.   However, the central circulation stayed intact and the storm jogged to the north before turning to the northwest upon reaching Cub...

Tropical Storm Isaac moved into the eastern Caribbean Tuesday afternoon and was moving westward during the evening.   The storm was getting better organized late in the evening, but the winds were not much different from earlier in the day.   It is only a matter of time before the winds respond to the drop in pressure.

There has been considerable concern about the future of this storm due to the impact it could have on Florida and the Republican National Convention in Tampa next week.   Any evacuation would greatly alter the plans for the convention.   A general idea of where the storm is going can be gleaned from the models.   However, the devil is in the details.   It is far too uncertain at this time frame to pin down where ...
