Hurricane-force winds extend outward up to 80 miles (130 km) from
the center and tropical-storm-force winds extend outward up to 255
miles (405 km).

RAINFALL:  Lorenzo is expected to produce total rain accumulations
of 3 to 6 inches over much of the western Azores and 1 to 2 inches
over the central Azores Tuesday and Wednesday.  This rainfall could
cause life-threatening flash flooding in the western Azores.

SURF:  Swells generated by Lorenzo are spreading across much of the
North Atlantic basin.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
