Typhoon Lingling
Saturday, September 7th, 2019“…….With maximum sustained winds of around 160 kilometers (95 miles) per hour, the typhoon is now headed toward South and North Korea.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image of the typhoon on September 6, 2019. The storm was moving north at 40 kilometers (25 miles) per hour and is expected to reach the Yellow Sea on September 7. It is then forecasted to make landfall in North Korea, according to the Japan Meteorological Agency.
The typhoon is expected to weaken as its outer bands interact with land on South Korea, but forecasters still expect torrential rainfall and damaging winds. Forecasters predict around 75 to 150 millimeters (3 to 6 inches) of rainfall and a storm surge, both of which may cause flooding and landslides.
Typhoon Lingling is the thirteenth tropical cyclone (typhoon or tropical storm) in the North Pacific this year. However, the Korean Peninsula typically sees just one landfalling storm per year…..”

NASA: Dorian skirts the eastern shoreline
Friday, September 6th, 2019After devastating the Bahamas and grazing Florida and Georgia, Hurricane Dorian rebounded and raked the coast of South Carolina with strong winds, heavy rains, and a storm surge. Wind, falling trees, and flooding damaged power infrastructure in coastal areas of the southeast U.S.
The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime composite image as the storm approached the coast at 3:42 a.m. Eastern Time (07:42 UTC) on September 5, 2019. At the time, Dorian packed maximum sustained winds of 115 miles (185 kilometers) per hour and was moving north at 8 miles per hour.
The VIIRS sensor observed thick cloud bands circulating around Dorian’s large eye, the part of the storm with mostly calm weather and the lowest atmospheric pressure. Hurricane eyes average about 20 miles (32 kilometers); the National Hurricane Center reported Dorian’s eye had a diameter of 50 miles (80 kilometers) around the time this image was acquired. Thinner clouds—part of the storm’s higher-level outflow—extended well inland across Georgia, South Carolina, and North Carolina.
The VIIRS image was captured by the sensor’s day-night band, which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as gas flares, city lights, and reflected moonlight. Infrared observations from VIIRS were used to enhance the visibility of clouds. Optical MODIS satellite data was layered into the image to make it easier to distinguish between ocean and land surfaces.
It is not possible to identify the locations of power outages based on the VIIRS night light image alone. However, as of 2 p.m. on September 5, several utility companies and Poweroutages.us were reporting more than 240,000 outages in South Carolina. The hardest hit area was Charleston County, where companies were reporting more than 130,000 outages.
In the coming days, forecasters expect Dorian to move near or over the coast of North Carolina and then toward New England and Nova Scotia.

Hurricane Dorian Lashing the Southeast US Coast; Tropical Storm, Hurricane, and Storm Surge Warnings in Effect from East Coast of Florida to Southeast Virginia
Thursday, September 5th, 2019Hurricane Dorian is expected to slowly move northwestward along the Florida east coast through Wednesday. Dorian will remain a dangerous hurricane, spreading impacts along and near the Florida east coast and the coasts of Georgia, South Carolina, and North Carolina through late week.

DISCUSSION AND OUTLOOK
———————-
At 500 AM EDT (0900 UTC), the center of Hurricane Dorian was located
near latitude 29.2 North, longitude 79.5 West. Dorian is moving

Dorian is forecast to move near or over the coast of South Carolina
and North Carolina Thursday through Friday morning.
Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts. Some weakening is expected during the next couple of days,
and Dorian is expected to remain a powerful hurricane during the
next few days.
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).
The minimum central pressure reported by an Air Force Reserve Unit
Hurricane Hunter aircraft is 963 mb (28.44 inches).
