Summary

[edit]
Description
English: Heading into the Labor Day holiday weekend in United States, citizens and government officials braced for a potent hurricane that has been intensifying in the tropical Atlantic Ocean. By the afternoon of August 30, 2019, Hurricane Dorian had reached category 3 intensity and was headed for the northern Bahamas and the east coast of Florida as a major hurricane, the first of the 2019 Atlantic season.

The photograph above was shot by an astronaut on the International Space Station at 11:12 a.m. Atlantic Standard Time (17:12 Universal Time) on August 29, 2019. At that time Dorian had maximum sustained winds of 85 miles (135 kilometers) per hour and a central pressure of 986 millibars, according to the National Hurricane Center. As of 2 p.m. AST (18:00 UT) on August 30, the center of the storm was about 445 miles (715 kilometers) east of the northwestern Bahamas and 625 miles (1005 kilometers) east of West Palm Beach, Florida. Sustained winds were measured at 115 mph (185 kmph) and the minimum central pressure was 970 millibars.

A key factor in the development of a hurricane is the warmth of the ocean surface. Warm water is the fuel that leads a storm to intensify, as heat and moisture move from the ocean to the atmosphere. This map above shows sea surface temperatures (SSTs) in the western Atlantic as of August 28, as well as population density in the U.S. Southeast and several Caribbean islands. Meteorologists generally agree that SSTs should be above 27.8°Celsius (82°Fahrenheit) to sustain and intensify hurricanes (although there are some exceptions).

NHC Forecasters reported on August 30: “Life-threatening storm surge and devastating hurricane-force winds are likely in portions of the northwestern Bahamas, where a hurricane watch is in effect...A prolonged period of storm surge, high winds and rainfall is likely in portions of Florida into next week, including the possibility of hurricane-force winds over inland portions of the Florida peninsula.”
