The current forecast track of Isaias keeps the most likely location of the heaviest rain and strongest wind gusts to the east/southeast of Binghamton near the Catskills/Poconos. Please stay up to date with the forecast throughout the day. If the storm track shifts slightly east/west, it will have an impact on the location of heaviest rainfall and strongest winds.
Isaias made landfall on the Carolina coast yesterday and is currently located in the Delmarva area. It will race northeast today. The heaviest rain likely continues through about 6 or 7pm east of Binghamton. Rain intensity, duration and amounts will be lower west of Binghmton. The strongest wind gusts will also occur during this period. The highest rainfall totals are still expected to be east of I-81, near the Catskills, with totals of 2-4”+. Rainfall totals will decrease as you head west. The lowest totals are expected in the Fingerlakes region with totals of up to 1”. Near Binghamton, we are likely to see about 1-2” of rain. There is the possibility for localized slightly higher totals.
The main threat from Isaias for our area is flash flooding. A flash flood WATCH is in effect today for Otsego, Broome, Chenango, Delaware, and Susquehanna counties. Major river flooding is NOT expected to be an issue today as river levels are relatively low for this time of year. Widespread wind damage and widespread power outages are also not expected.
Isaias moves out of our area late Tuesday into very early Wednesday morning, then we are in for a nice, quiet stretch of weather! A mix of sun and clouds with highs in the upper 70s and low 80s are expected Wednesday through Sunday.
