RAINFALL:  Ophelia is expected to produce total rain accumulations
of 2 to 4 inches over the southeastern Azores Saturday and Saturday

with Ophelia is expected to produce total rain accumulations of 1 to
3 inches over the other islands of the Azores. This rainfall could
produce flooding, especially over the southeastern Azores.
