light winds across lake erie today will gradually become
southwesterly at 10-15 knots wednesday afternoon as a strong cold
front moves into the western great lakes region. as this front
approaches and begins to move east across lake erie wednesday night,
an increased gradient will result in southwest winds increasing to
20-25 knots. as this front pushes east early thursday, winds will
become northwesterly at 15-25 knots, resulting in waves across the
central and eastern basin building to 4-6 feet. by thursday evening
the winds will shift back to southwesterly at 10-15 knots as another
cold front approaches from the west. this cold front is expected to
push east on friday into saturday. this will once again increase the
gradient and southwest winds to 25-30 knots ahead of the boundary
before shifting to northwesterly at 20-25 knots by friday night.
this will once again build waves to 4-6 feet. with the quick back to
back fronts, a long duration marine headline may be needed, but will
monitor timing for that. in addition, there is expected to be a high
risk of rip currents during this period. by sunday high pressure
returns and shifts the lake conditions back to calm.
