NOAA’s forecast for the coastal waters shows seas up to 30 ft on Sunday night. The NWS is currently predicting sustained winds of 40 mph at the coast with gusts to 60 mph. The strong wind and waves will reach the Washington coastline late on Sunday evening. Wave heights will approach 10 m (30 ft) in the open ocean on Sunday evening. The long fetch of strong winds to the south of the low will generate an impressive surf. The winds will be especially impressive over the open ocean near the low pressure center, sustained in the 50-70 mph range.
#WAwx /iovDoayL8C- Shannon O'Donnell October 23, 2021 Tree damage & power outages possible in communities downwind of the passes. Most models bring a burst of strong easterlies through the Cascade gaps morning through mid-day on Sunday. No matter WHAT the track of this deep low: #CascadiaWinds alert! The result will be strong gap winds through the Cascade passes, a phenomenon that is known locally as Cascadia winds. On Sunday, a strong pressure gradient will be directed east-to-west (perpendicular to the contours in the above maps).
Strong winds are driven by gradients between high and low pressure centers. But there are still a number of impacts to discuss. For reference, the famous 1962 wind storm bottomed out at 955 hPa.įortunately, this storm will be too far away from the coast to cause devastating impacts on par with our famous windstorms. This system is outside of the climatology for late October (1979-2009 is the reference period in the image below). Low pressure systems stronger than 960-970 hPa are unusual this close to our coastline at any time of year. The ECMWF ensemble members have reasonably high confidence in the intensity and position of the low at this time. The latest deterministic ECMWF run predicts a 943 hPa center on Sunday morning. Model forecasts of sea-level pressure are even lower than the first bomb cyclone on Friday. B1Gk2TR3K7- Scott Duncan OctoHow strong will the cyclone get? Nerd bit: I have contoured mean sea level pressure under the jet to show the text book interactions of the left-exit. Many countries use hectopascal for pressure, so that can be confusing for people who use bar.Explosive cyclogenesis under a rip-roaring jet stream in the Pacific is about to bring extreme weather down the west coast of North America. This pressure Conversion Calculator is a convenient way to convert hectopascal to bar unit. How much is 4372 hectopascal in bar? How big is 4372 hectopascal in bar? What is the hectopascal to bar conversion? How many bar is in 4372 hectopascal? The unit name is derived from the Greek βάρος, meaning weight. It is approximately equal to the atmospheric pressure on Earth at sea level. It is a measure of force per unit area, defined as one newton per square meter.Ī bar (symbol bar) is a non-SI unit of pressure, defined as exactly equal to 10⁵ Pa or 10⁶ dyn/cm² in CGS. This Measurement conversion calculator from 4372 hPa to bar in pressure Conversion.Ī hectopascal (hPa) is a decimal multiple of the pascal, which is the SI derived unit of pressure, stress, Young’s modulus and ultimate tensile strength. Pressure is commonly referred to hPa in some countries and bar in others. One hectopascal is equal to 0.001 bar, so 4372 hectopascal is equal to 4.372 bar.Ĭhange the values in the Measurement conversion calculator above to determine a different amount. How much is 4372 hectopascal in bar? Use this Measurement conversion calculator to convert 4372 hectopascal to bar. 4372 HECTOPASCAL to BAR pressure Conversion Table (Spell, Say and Pronounce In English Words)
