DISCUSSION AND OUTLOOK

become a hurricane later today and a major hurricane on Thursday.

HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Rosa will affect portions of the coast of
southwestern Mexico and the southern Baja California Peninsula
late this week and over the weekend.  These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
