NOAA National Hurricane Center stated at 11 a.m. the center of Tropical Storm Isaias was located about 90 miles (145 km) east-southeast of Brunswick, Ga., and about 220 miles (350 km) south-southwest of Myrtle Beach, S. Carolina. Isaias is moving toward the north near 13 mph (20 km/h), and this general motion is expected to continue today.
On the forecast track, the center of Isaias will pass well east of the Georgia coast through this afternoon. The center of Isaias will then approach the coasts of northeastern South Carolina and southern North Carolina within the hurricane warning area this evening.
Data from the reconnaissance aircraft and NOAA Doppler weather radars indicate that maximum sustained winds remain near 70 mph (110 km/h) with higher gusts
SECOORA put together this page to highlight data and information related to the Tropical Storm Isaias. It will be updated as new information becomes available and the track is more certain.

SECOORA gliders are capturing water column information ahead of Tropical Storm Isaias as it moves closer to the US. Data from gliders allows forecasters and scientists to improve predictions of the storm’s potential intensity.
Two gliders were deployed this month. The SECOORA glider Franklin (operated by UGA/SkIO) and the USF glider Sam off the East coast of Florida. Pictured above is their track on the IOOS Glider Data Assembly Center.
Follow the Data
Eyes on the Storm pulls data from within 50 miles of Tropical Storm Isaias path and showcases the highest wind speeds and wave heights and lowest barometric pressure. Assets in the storms path recorded a high wave heights and wind gusts off the coast of Florida. (pictured above).
Studying Coastal Change
On Saturday August 1, researchers at University of North Carolina Wilmington (UNCW) deployed water level sensors and sediment traps on on Masonboro Island, an uninhabited barrier island near Wilmington, NC. This research is part of a data set UNCW has been collecting since 2018 with bi-monthly surveys. They are looking at the impact of storms, like Tropical Storm Isaias, on barrier islands and the importance and timescale of natural recovery in between.

Ocean Heat Content
Ocean Heat Content (OHC) is an integrated measure of ocean heat relative to the depth where 78ºF/26ºC water is located in the water column (Figure 1). For hurricanes, the higher the OHC value, the more heat that is available to the hurricane often translating into a stronger hurricane. The converse is also true, the lower the value, the less OHC that is available for the hurricane and can weaken a hurricane.
The satellite image to the right provides estimates of both sea surface temperature (SST) and sea surface height. The information is used to determine the depth of the warm water below the surface. Knowing the depth of the warm water allows researchers estimate hurricane intensity since warm waters “fuel” hurricanes. This OHC research is operated by Nick Shay, University of Miami Rosenstiel School of Marine and Atmospheric Science.

The Coupled Northwest Atlantic Prediction System (CNAPS) is a three-dimensional marine environment nowcast and forecast system developed by the Ocean Observing and Modeling Group at North Carolina State University. This fully coupled ocean circulation, wave, and atmosphere model predicts ocean conditions based on real-time observations and computer programs.
Tropical Storm Isaias’s projected path is expected to impact the southeast U.S. coast through early next week.
As the storm moves north, explore mooring stations in North Carolina and South Carolina. The buoys are operated by UNCW Coastal Ocean Research and Monitoring Program.
In preparation for the storm, UNCW increased buoy reporting frequency to 15 minute intervals for the CAP2, FRP2, SUN2, and ILM. All NOAA National Weather Services offices have been notified of the increased data availability.
