Geomni crews are in the South Carolina area actively capturing post-storm imagery following Hurricane Dorian's passing through the Carolinas.

Hurricane Dorian has been brushing the Carolina coast since yesterday, bringing dangerous storm surge, heavy rainfall, tornadoes and damaging wind to the Carolinas. As of this morning, Dorian has decreased to a category 1 hurricane, with maximum sustained winds of 90 mph. As of 8 am this morning, various news outlets report that Dorian has made landfall in Cape Hatteras, North Carolina. Dorian has begun moving to the northeast at near 14 mph and should continue in this forward motion through Saturday. This means that Dorian should move out to sea today and it is expected to become a post-tropical cyclone by Saturday as it moves nearer to New England and Nova Scotia. Storm surge and tropical storm warnings remain in effect for those areas.

Geomni has been closely monitoring this situation for days, making sure that our fleet of aircraft were staged and ready to respond quickly. The imagery capture team is already in the area collecting post-CAT imagery along the South Carolina shoreline. Plans to collect imagery along the North Carolina shoreline will be executed as soon as weather conditions clear up. Post-CAT imagery should be available in the coming days.

Hurricane Dorian underwent a period of brief re-intensification overnight and went back up to a category 3 hurricane, but has already weakened back down to a category 2 this morning. Dorian is now moving to the north-northeast at around 8 mph with wind speeds of 110 mph. The storm is forecasted to move very close to the coast of South Carolina today, and then move near the North Carolina coast tomorrow and Friday, so a landfall in either of these regions is not outside the realm of possibility.

Tornado watches are in effect for parts of northern South Carolina and eastern North Carolina through today, a common occurrence in the outer rainbands of hurricanes as they approach land. A number of damaging tornadoes have already been reported as of this morning.

As of this writing, Hurricane Dorian is now a category 2 hurricane with wind speeds of 105 mph, moving to the north-northwest at 9 mph up the southeastern United States coast. Doria is approximately 95 miles east of Daytona Beach, Florida and will continue to move along the northern Florida and Georgia coasts today. It should continue moving in this parallel direction until tomorrow, when it will shift and start moving to north, then the northeast on Thursday. 

Despite remaining off the coast of Florida, the entire southeast region, including Georgia and the Carolinas, faces threats from strong winds, storm surge and flooding, perhaps even tornadoes. The center of Dorian is forecast to move near or over the Carolinas Thursday into Friday.

Hurricane Dorian is expected to maintain its category 2 strength through today; after that, it should gradually weaken. Should Dorian make landfall in the Carolinas later this week, it would likely be as a category 1 or 2 hurricane. Dorian is expected to weaken further after Friday as it continues to move in a northeasterly direction away from the U.S. coast.

Hurricane Dorian is finally pulling away from the northern Bahamas this morning, as well as picking up speed and size. It still remains a very dangerous hurricane, with hurricane-force winds extending outward up to 60 miles from its center. Dorian has begun its predicted turn to the north, moving northwest at 2 mph, and it will move dangerously close to Florida by this evening.

According to the most recent forecasts, it still remains unclear if Dorian will ultimately make landfall. The most likely scenario expects Dorian to continue moving up the southeastern U.S. coast without ever making landfall, eventually making a turn to the northeast to move out to sea. Even if this scenario is confirmed, significant impacts may occur along coastal regions, from Florida all the way up to the Carolinas. These impacts include wind gusts, heavy rainfall, swells and storm surge, and even tornadoes.

Geomni's fleet of aircraft remain staged and ready should Hurricane Dorian make landfall in the U.S.

Dorian was just downgraded to a category 4 hurricane with wind speeds of 155 mph and gusts up to 190 mph. This is not good news just yet, as Dorian is still a very dangerous major hurricane that has all but stalled over the Bahamas today at speeds of 1 mph. Yesterday, it made landfall in the Abacos Islands as a destructive category 5 hurricane, battering the region with powerful wind, rainfall and storm surge. Today, it is expected to move over Grand Bahama Island and inch closer to the Florida peninsula.

A great deal of uncertainty remains with Dorian's track after today. Strong pressure to Dorian's north is still expected to weaken today, allowing it to start making a turn north; it would also being to pick up more speed again. If this happens, Florida could largely be spared from the worst of Dorian making landfall as a major hurricane, and Dorian instead would skirt the southeast coast and make landfall in the Carolinas. Florida could still feel some wind and storm surge effects, but it would not be nearly as catastrophic as experiencing Dorian's direct landfall. Should Dorian move along this predicted track, it would make landfall in the Carolinas as a category 1 or 2 hurricane.

Hurricane Dorian has evolved into an extremely dangerous major category 5 hurricane, with maximum sustained wind speeds reported of 180 mph. It's still moving west but has slowed down significantly. This trend should continue for the next day or so before it turns gradually north. This means that landfall along the east coast is possible anywhere from Florida all the way up to North Carolina. 

Today, Dorian is expected to have catastrophic effects as it moves over the Northwestern Bahamas, including the Abacos and Grand Bahama Islands. Wind gusts of 100 mph have already been reported and the areas could experience life-threatening storm surge of up to 23 feet in some areas as Dorian moves slowly over the islands for the next 24 hours.

Dorian will remain a very powerful and destructive hurricane during the next few days. The system has also grown in size; hurricane-force winds extend outward up to 45 miles from the center, and tropic-storm-force winds extend out to 140 miles.

Geomni continues to monitor Hurricane Dorian's daily developments in anticipation of capturing post-CAT aerial imagery. Here is the latest update.

Dorian strengthened to a category 3, then a category 4 hurricane yesterday. According to the latest reports from NOAA, Dorian now has sustained winds of 145 mph and is moving west at 12 mph. It's expected to remain a dangerous major hurricane through the weekend.

There has been a significant change in the hurricane's forecasted track. The area of high pressure that is currently preventing Dorian from moving north could weaken, meaning that it could turn and start moving north toward Georgia and the Carolinas rather than making landfall in Florida. The uncertainty around when and where this turn is going to take place will have a dramatic impact on where Hurricane Dorian ultimately tracks and makes landfall.

Hurricane Dorian originated as a tropical storm on August 24th in the southern North Atlantic Ocean. Since then, it's been increasing in both strength and size as it moved over the Windward Islands, including St. Thomas, and the U.S. and British Virgin Islands. Puerto Rico was able to dodge the worst effects of Dorian as it became better organized and strengthened to a hurricane.
According to the latest forecast from the National Hurricane Center, dry air in the Atlantic will dissipate, giving Dorian a chance to strengthen to a Category 3 major hurricane as it continues to move over warm, open waters. An area of high pressure to its north will push the storm westward - directly into the path of the northern Bahamas and the Florida peninsula. 
Geomni has already initiated its aerial imagery capture operations in anticipation of Dorian's likely landfall so that we will be prepared to respond to this storm quickly.
