Isaias was over the southern and central Bahamas at the time, and generating soaking rains.
“The anvil of the system extended northwestward across North and South Carolina with maximum cloud heights estimated at 16-17 km (~10 to ~11 miles),” said Natalie Tourville of the Cooperative Institute for Research in the Atmosphere, Colorado State University, Fort Collins. NASA’s Aqua satellite provided visible and infrared views of Isaias and found the storm a little more disorganized–an indication that it had weakened from a hurricane to a tropical storm. For an updated list of hazards, visit the NHC website. Later in the day, by 5 p.m. EDT, deep convection continued to increase and a band of thunderstorms developed over the southwestern portion of the broad circulation. At the time of the image, Isaias had not yet reached Turks and Caicos. The entire East Coast will have to watch Isaias closely for the next few days. The higher the cloud tops, the colder and stronger they are.
Reports from the reconnaissance aircraft indicate that the minimum central pressure is 990 millibars.
© Copyright TWC Product and Technology LLC 2014, 2020. On Thursday, Isaias' exterior slammed Puerto Rico before it went over the Dominican Republic, all as a tropical storm. Re-strengthening is forecast on Friday into Friday night. A tropical storm warning is in effect for... * North of Ocean Reef to south of Boca Raton in Florida. Where Isaias will affect the US, and how intense it will be, was still uncertain Friday morning. CNN's Judson Jones, Sara Tonks, Madeline Holcombe, Dakin Andone, Joe Sutton, Hollie Silverman and Dianne Gallagher contributed to this report. The hurricane center said Isaias will approach the southeast coast of Florida tonight and move near or along the east coast of Florida Sunday and Sunday night. At 5 a.m. EDT (0900 UTC) on Aug. 6, the center of Post-Tropical Cyclone Isaias was located near latitude 47.5 degrees north and longitude 71.8 degrees west. Kerner said the county is well prepared and the shelters, and would have temperature checks and be divided into family units. The hardware stores, pharmacies and supermarkets would be allowed to open.
", "When you're not testing is also a concern," he added. Water vapor analysis of tropical cyclones tells forecasters how much potential a storm has to develop.
The following rainfall accumulations are expected along and near the track of Isaias: central and eastern North Carolina into the Mid-Atlantic: 3 to 6 inches, isolated totals a maximum of 8 inches; eastern New York into Vermont: 2 to 4 inches, isolated maximum totals 6 inches; and western Connecticut, western Massachusetts, New Hampshire and western Maine: 1 to 3 inches.
Cloud top temperatures provide information to forecasters about where the strongest storms are located within a tropical cyclone. NASA research has shown that cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain. Florida closed some state-supported Covid-19 drive-thru and walk-up testing sites on Thursday in anticipation of the storm. In addition to Isaias forecasters are tracking what was Tropical Depression 10 near Africa, which has been downgraded to a remnant low, and a tropical wave in the central Atlantic that could become a depression early next week.
A Hurricane Warning is in effect for South Santee River, South Carolina to Surf City, North Carolina. Tropical cyclones/hurricanes are the most powerful weather events on Earth. NASA provides that data to forecasters at NOAA’s National Hurricane Center or NHC so they can incorporate in their forecasting. That is about 55 miles (90 km) north-northwest of Quebec City, Quebec, Canada. NASA’s Aqua satellite passed over Isaias on Aug. 4 at 2:50 a.m. EDT (0650 UTC). NASA’s Aqua satellite passed over Hurricane Isaias on July 31 at 3:20 a.m. EDT (0720 UTC), and the Moderate Resolution Imaging Spectroradiometer or MODIS instrument gathered water vapor content and temperature information. The storm developed into Tropical Storm Isaias on July 29.
NASA’s Aqua satellite’s MODIS instrument also used infrared light to analyze the strength of storms in Tropical Storm Isaias.

NHC forecasters noted, “On the forecast track, the center of Isaias will move near or over Andros Island in the Northwestern Bahamas this morning and continue to move near or over the rest of Northwestern Bahamas later today, and move near the east coast of the Florida peninsula tonight through Sunday (Aug. 1).”.
The country's health minister, Renward Wells, said Friday that initial confirmed cases of the second wave were connected to "individuals from Grand Bahamas who traveled from the United States.".
Isaias weakened to a tropical storm on Saturday and looked a bit ragged as it moved closer to South Florida.
ET, August 1, 2020 Isaias is still expected to strengthen into a hurricane overnight Temperature is important when trying to understand how strong storms can be.
