000 ABNT20 KNHC 150554 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Wed Sep 15 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center has issued its last advisory on Tropical Depression Nicholas, located just west of the Texas and Louisiana border. Future advisories on Nicholas will be issued by the Weather Prediction Center. Showers and thunderstorms associated with a low pressure area located a few hundred miles south of the Cabo Verde Islands continue to show signs of organization. Environmental conditions are expected to remain conducive for development, and a tropical depression is likely to form during the next couple of days while the system moves generally westward at about 15 mph across the eastern tropical Atlantic Ocean. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...90 percent. A trough of low pressure located a few hundred miles northeast of the central Bahamas is producing a large area of disorganized showers and thunderstorms. Environmental conditions appear marginally conducive for gradual development during the next few days, and a tropical depression is likely to form while the system moves north-northwestward to northward across the western Atlantic. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...70 percent. A tropical wave is expected to emerge off of the west coast of Africa toward the end of the week. Thereafter, environmental conditions are forecast to be conducive for development while the system moves generally west-northwestward to northwestward over the far eastern Atlantic. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...20 percent. && Public advisories issued by the Weather Prediction Center on Tropical Depression Nicholas can be found under AWIPS header TCPAT4, WMO header WTNT34 KWNH, and on the web at http://www.wpc.ncep.noaa.gov. $$ Forecaster Papin

Tropical Depression Nicholas Forecast Discussion Number 12
2021-09-15 04:35:42| National Hurricane Center (Atlantic)
Issued at 1000 PM CDT Tue Sep 14 2021 000 WTNT44 KNHC 150235 TCDAT4 Tropical Depression Nicholas Discussion Number 12 NWS National Hurricane Center Miami FL AL142021 1000 PM CDT Tue Sep 14 2021 Satellite imagery, radar data, and surface observation indicate that the center of Nicholas is over the Beaumont/Port Arthur area of southeastern Texas. The cyclone is currently comprised of a large swirl of low- to mid-level clouds and showers, with a few patches of deep convection well removed from the center. The initial intensity of 30 kt is based on a combination of Doppler radar data and surface obs, and these winds are mainly over water to the southeast of the center. Nicholas should continue to weaken due to strong shear, dry air entrainment, and land interaction, and the cyclone is forecast to degenerate to a remnant low after 24 h and dissipate completely by 72 h. It should be noted that some of the track guidance models show enough south of east motion to bring the center back over the Gulf of Mexico in a day or two. However, even if this should occur the shear and dry air should prevent any re-development. The initial motion is 060/5. While there is some spread in the guidance, it generally agrees on a slow eastward motion for 36 h or so, followed by a northward drift. The new forecast track has only minor changes from the previous track. Although the winds associated with Nicholas are subsiding, due to the forecast slow motion, heavy rainfall and a significant flash flood risk will continue along the Gulf Coast for the next couple of days. The is the last advisory on Nicholas issued by the National Hurricane Center. Future information on this system can be found in Public Advisories issued by the Weather Prediction Center beginning at 4 AM CDT, under AWIPS header TCPAT4, WMO header WTNT34 KWNH, and on the web at http://www.wpc.ncep.noaa.gov. Key Messages: 1. Heavy rainfall will impact areas across southern and central Louisiana, southern Mississippi, far southern Alabama, and the western Florida Panhandle through early Friday. Significant rainfall amounts are expected, potentially resulting in areas of life-threatening flash and urban flooding across these areas. Widespread minor to isolated moderate river flooding is also possible. 2. Storm surge inundation along the coasts of upper Texas and southwestern Louisiana will diminish tonight. 3. Wind gusts to tropical-storm force are possible for a few more hours along portion of the Louisiana and upper Texas coasts.
