"Tropical Storm Fay is strengthening again, taking advantage of the deep, warm waters between Cuba and Jamaica. Though Fay's top winds are rated at just 45 mph, the storm has an increasingly impressive appearance on visible satellite loops. The circulation is expanding and intensifying, the upper-level outflow is expanding to the north and southeast, and low-level spiral bands are beginning to develop. Assuming Fay can dodge the southeast tip of Cuba without weakening, which appears likely to me, this should be a Category 1 hurricane by Sunday evening."
