Tropical Depression 16 was officially named this morning, Sept. 28 at 11 a.m. EDT by NOAA's National Hurricane Center in Miami, Fla. Many watches and warnings have also already been posted this morning.

In the U.S., Florida is under a Tropical Storm Warning and Watch. A Tropical Storm Warning has been issued for the Florida coast from Jupiter Inlet southward to East Cape Sable, and for all of the Florida Keys, including Florida Bay and the Dry Tortugas. A Tropical Storm Watch has been issued for the west coast of Florida from north of east Cape Sable to Chokoloskee and for the east coast of Florida from north of Jupiter Inlet to Sebastian Inlet.
The Atmospheric Infrared Sounder instrument, known as AIRS has the ability to determine cloud top and sea surface temperatures from its position in space aboard NASA's Aqua satellite. Cloud top temperatures help forecasters know if a storm is strengthening or weakening. When cloud top temperatures get colder it means that they're getting higher into the atmosphere which means the "uplift" of warm, moist air is stronger and it will form stronger thunderstorms (that power a tropical cyclone). When cloud-top temperatures warm up it means that the cloud tops are lower than they were before, indicating that the storm is weakening.
When the Aqua satellite passed over Tropical Depression 16 (TD16) from space on Sept. 28 at 0635 UTC (2:35 a.m. EDT) the AIRS instrument took the temperature of the cloud tops in the storm and found them to be as cold as or colder than -63 Fahrenheit throughout a very large area within TD16, indicating the storm had a good amount of energy to power it up. The area of strong thunderstorms in the AIRS images is quite large, and TD16 is already raining on western Cuba.
The Geostationary Operational Environmental Satellite known as GOES-13 flew over Tropical Depression 16 on Sept. 28 at 1425 UTC (10:25 a.m. EDT) as it strengthening into a depression. GOES-13's visible imagery showed a large extent of cloud cover, spanning over Cuba and Jamaica, the Cayman Islands and northeastward into south Florida.
The National Hurricane Center (NHC) in Miami, Fla. noted this morning, Sept. 28 at 8 a.m. EDT that TD16 is going to bring some heavy rains and squally conditions in the Caribbean. NHC said, "Heavy rains and strong gusty winds to tropical storm force are expected to affect the Cayman Islands, Jamaica and Cuba today. These weather conditions are likely to spread over the Florida Keys, southern Florida and the northwestern Bahamas later today and Wednesday."
During the morning hours of Sept. 28, the strongest winds were happening about a couple of hundred miles east and south of the Isle of Youth, Cuba and Grand Cayman. If TD16 strengthens into a tropical storm, it would be named Nicole.
South-southwesterly vertical wind shear associated with a large upper-level trough moving into the southeastern U.S. is expected to limit the storm's intensification, although it is near tropical storm-force this morning. The projected track of the TD16 takes it in a north-northeasterly direction across Cuba toward southeastern Florida.
Meanwhile, there's another female named storm that's still making waves in the Atlantic Ocean basin, Julia. However, Julia is just a remnant low pressure area and is about 150 miles south-southeast of Bermuda. This remnant low is moving west-northwest near 15 mph and is not in a good environment for redevelopment. The NHC gives Julia's remnants a meager ten percent chance of redeveloping in the next 48 hours, so TD16 is the one to watch.

Sea ice hit record lows in November

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
