515 AM EDT Thu Jun 20 2019

This Hazardous Weather Outlook is for western and north central New
York.

.DAY ONE...Today and tonight.

Multiple rounds of moderate to heavy rain can be expected today as
low pressure will pass by just to our south. While basin average
rainfall amounts will generally average a half to three quarters of
an inch, there will be the potential for localized amounts of up to
an inch and a half. Most tributaries will be able to handle this
amount of rain if it falls over a span of multiple hours, but there
will be a higher risk for flash flooding in urban centers and in areas
with terrain.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

Hazardous weather is not expected at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
