my fellow excessive sweaters, rejoice!! the first comfortable air mass on the horizon since july 4, and maybe the second time we've seen dew points below 60 in about a month. 😍

In a continuation of a weeks-long parade of hurricane-force lows across the N Pacific... owing to dynamic fetch and 90 kt winds, the low now crossing the dateline along 40N set to be a prolific wave producer, with 60 ft significant wave heights now in the forecast. Incredible stuff.

Just incredible views from Himawari-9 ProxyVis. From the NFDHSFEPI: ".LOW 45N167E 942 MB MOVING NE 25 KT. WITHIN 240 NM S AND SW QUADRANTS WINDS 75 TO 100 KT. SEAS 38 TO 52 FT." Should get ASCAT overpasses soon, but those saturate around 85 kt. We shall see...

100 kt (115 mph) sustained winds, 16 meters (>50 ft) significant wave heights in the west/central Pacific. an outstanding forecast 5+ days out. marine traffic avoidance pretty apparent. some of the holiday season gifts inbound for the west coast will be rockin and rollin.

as forecast: explosive cyclogenesis now underway across the eastern pacific with 68 mb pressure falls forecast over the next 24 hours (1011 mb to 943 mb)! satellite imagery throughout the day will be something to behold 🌊🌊

Good catch, Dave! I certainly believe so

Beast of a low still intensifying offshore the Carolinas, displaying the tell-tale signs of a very potent system. Milky and hazy appearance near the sting jet / descending ccb likely sea spray, indicative of some serious winds in the S/SW quadrant. Loads of lightning, too! #MarineWx

sunrise over our potent little low developing off the NC coast this morning, buoy 41025 / diamond shoals already gusting to storm force 👀

rockin' and rollin' offshore, 50 kt winds and 25 ft seas 🌊- interestingly, energy sheds northeast from this system and helps amplify the big blow headed for the UK over the weekend

Storm-force winds returned in the ASCAT overpasses this morning associated with the (very non-tropical looking) AL99 🌬️🌬️

Decent shot Monday for daily record highs at DCA (100) and IAD (98); I hope Tuesday RMAXs (104) are out of reach. Brutal summer surge on the way regardless. 🥵 Cold front Wed night and the next air mass Thu/Fri will be glorious. Put in your leave requests now!
