The approaching February full moon – the Snow Moon – will bring a round of higher than normal tides next week. The tide peaks on Wednesday the 20th, with a late morning / midday tide of 12.11 feet at Barnstable Harbor. Thursday’s midday tide is just a smidge lower, with a predicted value of 12.01 feet.
We’ll have to keep an eye on the weather next week as any onshore flow will enhance these values and likely lead to at least some nuisance variety coastal flooding. Right now, a relatively weak storm system is forecast to move through the area Wednesday and Thursday, bringing at least some easterly flow. Were this storm center to become a more substantial system, a more serious issue would be in the cards.
Case in point…fairly innocuous storm Tue PM was still enough to create ~1.5' surge. A similar evolution on a 12' tide would bring a place like Boston to ~13.5'…which is a solid foot above minor flood stage. Worth monitoring with quiet weather the next several days pic.twitter.com/DX5nYW97YB
