Because hurricane-force winds extend outward up to 60 miles (95 km) from the center, and tropical-storm-force winds extend outward up to 175 miles (280 km), Daytona was experiencing those tropical-storm-force winds at 8 a.m. EDT. A Flash Flood Watch is in effect through this evening. In part because of Hurricane Dorian’s forward motion during the past two days, the recent rainfall totals have remained below the 36-inch accumulation observed when Dorian was stalled over the Bahamas.

At the same time, the geographic extent of tropical-storm strength winds increased significantly. Earlier in the week, NOAA’s National Hurricane Center was monitoring a low-pressure system in the Gulf of Campeche that has now moved along the Texas and Louisiana coastlines, bringing heavy rainfall. IMERG is used to estimate precipitation from a combination of passive microwave sensors, including the Global Precipitation Measurement (GPM) mission’s core satellite’s GMI microwave sensor and geostationary IR (infrared) data. NASA’s Goddard Space Flight Center. Interests along the Gulf coast of Mexico should monitor the progress of this system.”, By Rob Gutro  This image shows estimated rainfall accumulations for the region affected by Hurricane Dorian over a 24 hour period from August 27th - 28th.

“. The center of Dorian is forecast to move near or over the coast of South Carolina and North Carolina Thursday through Friday morning. GPM also utilizes a constellation of other satellites to provide a global analysis of precipitation that are used in the IMERG calculation. It may be hard to believe after recent rains, but 2019 will go down in history for record-setting low rainfall totals on the Harbor.

The storm-total rainfall at a particular location varies with the forward speed of the hurricane, with the size of the hurricane's wind field, and with how vigorous the updrafts are inside the hurricane.

As of early on August 30, Hurricane Dorian has been producing 2 to 6 inches of rain along the path of its inner core for several days. Hurricane Dorian continues to generate tremendous amounts of rainfall, and has left over three feet of rain in some areas of the Bahamas and is now lashing the Carolinas. The National Weather Service noted that “heavy to excessive rainfall threat shifts from the lower Mississippi Valley on Wednesday into the Central Gulf Coast states and eventually the U.S. Southeast by the end of the week.” For updated forecasts, visit: www.weather.gov, By Rob Gutro/with forecast information from weather.gov System 91L is an area of tropical low pressure located in the Bay of Campeche. Those strongest storms were located just off the coast of the state of Campeche and the eastern part of the state of Tabasco. In part because of Hurricane Dorian’s forward motion during the past two days, the recent rainfall totals have remained below the 36-inch accumulation observed when Dorian was stalled over the Bahamas.
