SURF: Large swells generated by Teddy are reaching the Lesser
Antilles and the northeastern coast of South America and should
spread westward to the Greater Antilles, the Bahamas, Bermuda, and
the east coast of the United States by the weekend. These swells
are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
