    Heat Heads East Followed by Moisture

    Isaac's winds are weakening in terms of speed, but it remains a potent rain producer. It will move northward through the lower Mississippi Valley, then eventually turn more to the east. Its precise track will then determine where most of the rain falls. This video shows how this could unfold.

    The tropics remain active, and an area of disturbed weather in the eastern Atlantic could become Leslie. It has already been picked up by the National Hurricane Center and is called Tropical Depression 12. At 11 a..m. EDT, it was at latitude 14.1 North and longitude 43.4 West. Computer models have offered various scenarios for this storm, and we'll be watching it. At 11 a.m., it was 2,475 miles east-southeast of Cape Hatteras, N.C. I used that point just to show how far away it is from the East Coast, not to suggest where it is going.

    Meanwhile, a hazard has popped up today along Lake Michigan. The southerly flow behind the high now in the Northeast is going to be strengthening. The increase in heat will make swimming attractive, but the National Weather Service office in Grand Rapids considers the situation to hazardous. The waves will be higher than usual in summer and will be spaced a shorter distance apart than usual. The various hazards this poses are depicted on this map:
