Latest data The upper plot compares raw data (blue) and forecast tide (red). When the two curves are aligned there is no storm surge, which is the elevation or depression of sea level as a result of meteorological conditions. But if the raw data lie above or below the forecast tide, it means we have positive or negative storm surge. The lower plot compares storm surge (SS) with inverted barometer (IB), which is derived from atmospheric pressure. When the two curves are aligned it means that the storm surge is being driven by local pressure changes.

RSS stands for Really Simple Syndication. It's a way of separating web content from the websites they came from and allowing people to mix content from different sites or to receive content as soon as it is updated. RSS documents, known as "feeds" or "channels", includes full or summarized text, plus metadata (information about information) such as publishing dates and authorship. RSS feeds can be incorporated into other sites, or read using software called "RSS readers" or "aggregators", which can be web-based, desktop-based, or mobile-device-based.
