wind speed is 80 kt with gusts to 100 kt. Dora will continue on 
a WNW track then begin a weakening trend Tuesday as the system 
moves over cooler waters and into a more stable environment. 
Large swell generated by Dora is affecting the coast of SW 
Mexico expected to spread northwestward and affect portions of
the southern Baja California coast Tuesday. Heavy rainfall may 
affect coastal sections of Guerrero and Michoacan in Mexico.
Scattered to numerous moderate convection is occurring within 
180 nm of center. See latest NHC Forecast/Advisory under 
AWIPS/WMO headers MIATCMEP4/WTPZ24 KNHC for more details.
