410 PM EDT Sun Sep 23 2018

...INCREASING WAVES LATE TONIGHT INTO TUESDAY...

.Fresh easterly flow will gradually veer to southeasterly through 
Monday. Onshore flow will build significant wave heights to several 
feet during this time. Small craft advisories therefore remain in 
effect. By Monday night...the long-duration southeast wind will 
build maximum wave heights into the 10 to 15 foot range over much of 
central Lake Huron. Wind will then diminish on Tuesday as low 
pressure moves over the waters. However, moderate to fresh northwest 
flow will quickly redevelop on Wednesday as a large Canadian high 
builds from the west.
