Invest #96L helping spark showers across Puerto Rico. System had nice ball of convection overnight but at sunrise that collapsed. Possibly due to mid-level dry air. If storm-less spin can form new showers may get brief system. But strong cold front Tuesday sends away. 29-Oct2023

Tropical Storm #Tammy redevelops about 215miles(350km) East of Bermuda. Winds 65mph(100km/h), drifting Northwest 3mph(6km/h). Expected to turn back East and out to sea as slowly weakens. 12pADT/11aEDT 27-Oct2023

There is a small window for #Tammy to reacquire tropical / subtropical characteristics in a few days however. This is reflected in the 8aEDT Tropical Weather Outlook map from NHC Thursday morning with 30% chance of that occurring. Bermuda could see rain/wind regardless 26-Oct2023

#Tammy has become an Extratropical Cyclone (former tropical system (post-tropical) that now derives it's energy from baroclinic process rather than warm waters; running into a frontal boundary, wind shear and dry air). Therefore no more advisories to be issued by NHC. 26-Oct2023

Appears #Tammy (Atlantic) is interacting with frontal boundary, nearby dry air & wind shear this evening - loosing tropical characteristics. 25Oct2023

Hurricane #Otis - brief destructive system, now no more. 25Oct2023

Hurricane #Otis makes landfall near Acapulco Mexico as Cat5 with 165 mph (270 km/h) winds. Now rapidly weakening as hits high terrain just inland. 25Oct2023 135aCST/335aEDT

Those wobbles will make all the difference tonight. Hurricane winds extend out to 30miles(45km) from center. 24Oct2023 9pCST/11pEDT #Otis

Hurricane #Otis unexpectedly rapidly intensifies Tuesday afternoon into Cat4 145mph(230km/h) winds about 85miles(135km) SSE of Acapulco Mexico in East Pacific. Hurricane winds extend up to 30miles(45km) from center. Landfall expected early Wednesday along Mexico coast. 24Oct2023

#TD21 formed earlier this week in the Southwest Caribbean, moving into the North-Central Nicaragua coast Tuesday. The resulting scattered showers may eventually form a new system along the Southern Mexico coast in the Eastern Pacific later this week/weekend. 24Oct2023

Hurricane #Tammy continues NE in Atlantic. Intensity expected to peak within 24 hours then steady weakening. Transitions into non-tropical low. Low may turn back West. Models split on eventual track. Many models turn out to sea eventually, a few continue W/SW though. 24Oct2023

With Watches posted for Hurricane #Norma in the Eastern Pacific & Tropical Storm #Tammy in Atlantic, NHC updates storm stats & maps every three hours: https://hurricanes.gov (US gov), just below the main map image at:
EDT/AST/MST: 2,5,8,11am/pm
CST/MDT: 3,6,9,12am/pm

Tropical Storm #Tammy about 430miles(690km) East of Barbados. NOAA/USAF Hurricane Hunter planes arriving in Caribbean this evening for Thursday flights in storm. Expected to clip NE Caribbean Friday/Saturday as turns up between High pressure & approaching cold front. 18Oct2023

Norma races to Hurricane status. NHC with Cat3 Thursday. Then wind shear likely starts weakening trend. Nears tip of Baja peninsula this weekend. Models either curve near/across & into Western Mexico or meander near there & then into Mexico. 18Oct2023

Tropical Storm #Tammy forms in the Atlantic. NHC will begin advisories by 5pEDT/AST 18Oct2023

Uncertainty in eventual track & strength of invest #94L. May warrant PTC designation sometime Wednesday so that Tropical Storm Watches can be issued(poss impacts by Fri) PTC allows for typical NHC products to be issued (Watches, cone map, etc.) prior to storm formation. 17Oct2023

Tropical Storm #Sean just scattered showers. No more advisories by NHC. Northeast Caribbean should continue to monitor invest #94L behind it for potential impacts this weekend. System likely to develop by end of the week and may clip the region as turns up. 16Oct2023

Invest #94L healthy Saturday morning. Large, will take time to spin up. Leeward Islands / Puerto Rico area should monitor as may near region late this week / next weekend where conditions look favorable for strengthening. Eventually turns North, models differ on when. 14Oct2023

Tropical Storm #Sean was finally able to develop convection over its core overnight, but as the sun rises those storms are fading. Has reached dry air. Will be lucky to make it past Sunday. 14Oct2023
