NWS Quantitative Precipitation Forecasts
Many states around the country use total rainfall in a 24hr period as a trigger for opening and closing shellfish harvest areas and for issuing warnings for swimming beaches. This product provides graphical guidance of expected, cumulative rainfall several days in advance through google earth. Follow these instructions to download Google EarthTM and to learn how to work with the QPF kml files.
Doubling Time of Vibro parahaemolyticus (Vp) in oysters
Vibro parahaemolyticus has one of the fastest growth rates of all estuarine bacteria, and the population can replace itself, or double every hour at 90°C. This product uses modeled air temperature from the North American Mesoscale to force a statistical growth rate equation (USFDA 2005) for Vp. The spatially explicit graphical display allows users to determine where and when the highest doubling times will occur every hour, out to 72 hrs in advance to plan harvest and refrigeration strategies.
NWS Three Month Outlooks
For longer range planning for an upcoming growing or beach season, helpful forecasts are provided by the NWS Climate Prediction Center. These 3 month outlooks for temperature and precipitation, give probabilities of above average, normal or below average temperatures and rainfall with respect to a recent 30 year climatology.
As a work in progress, current Vibrio models displayed here are considered experimental products, and thus NOAA will not be held liable from issues arising from their interpretation and use.
