Latest Marine Discussion:

.MARINE... A cold front currently pushing eastward from the Alleghenies will eventually lead to increasing winds over the waterways. This brings a shift to northwesterly flow along with gusts of 20 to 25 knots, occasionally to near 30 knots at times. Small Craft Advisories are in effect for all waters through the mid-evening, while continuing into the night over the southern waters. For the remainder of Tuesday into Wednesday, the weaker gradients accompanying the Canadian high pressure will favor gusts of around 5 to 10 knots. SCA conditions are possible again during the second half of the week (i.e Thu afternoon into Fri morning). Update as of: 924 AM EDT Mon Sep 14 2026
