2 new NY #tornadoes along with multiple possible tornadoes found on July 22, 1926: A strong (~F2) multi vortex tornado that severely damaged homes, destroyed barns and orchards & injured 5 people between Italy and Keuka Park, and a waterspout (~F1) that was observed making (1/2)
Account of a likely #tornado that was embedded in a QLCS that affected areas south of Boston (esp. Weymouth) in late August of 1920. The tornado was not weak, destroying barns and dwellings (likely meaning serious damage to homes) which is likely indicative of low-end F2 intensity. #Wxhistory #WxSky
On June 26, 1926 a strong tornado not present in records (likely low end F2) unroofed multiple brick buildings and caused other widespread damage in Utica NY and the nearby town of Schyler. The old hospital grounds were covered in downed trees afterward and 3 children were injured. #wxhistory #wxsky
Accounts of 2 #tornadoes which struck New Jersey around July 8, 1900. One unroofed houses near Freehold (~F1) while the other was much more destructive, destroying cottages and severely damaging homes at Long Branch / Elberon (~F2). One fatality occurred due to sustained injuries.

February 1, 2007:
The Enhanced Fujita scale became operational in the US. Unlike the original scale that had been utilized since 1971, the update better reflected examinations of tornado surveys to align wind speeds more closely with associated storm damage.

Terra MODIS RGB composite satellite image of Tropical Storm Tammy at 16:23 UTC on October 5, 2005. The storm's low-level center is visible just off the coast in the Daytona Beach area in central/northeast FL. Disorganized deeper convection is more broadly distributed to the north and east of the center. The storm's intensity at the time shown is 40kt (1004mb pressure).
NOAA WPC rainfall map for Tammy from October 4-7, 2005. The storm track begins near Andros Island, Bahamas, closely parallels the FL east coast, crosses the coast near Jacksonville, performs half a counterclockwise loop, exits into the Gulf of Mexico near Destin, FL, and ends. Rainfall totals of 1-3" are spread across the FL peninsula. The highest rainfall occurred in southeastern Georgia with a maximum of 14.48" (368mm) in Darien. Small localized areas of 7"+ fell in east-central SC. Not shown are rainfall totals associated with the cold front that passed through the northeastern US days later.
OTD in 2005: Short-lived Tropical Storm Tammy makes landfall near Jacksonville, FL. Though 10-15" (250-375mm) of rain fell in GA, damage was relatively minor. Tammy's remnants were later absorbed into a cold front that brought 10+" of rain to parts of the mid-Atlantic and New England. #wxhistory
Terra MODIS infrared satellite image of Category 1 Hurricane Philippe at peak intensity in the open Atlantic, around 01:41 UTC September 20, 2005. The intensity of the storm is 70kt (985hpa). The storm structure consists of a large, concentrated blob of convection. Very cold cloud tops (gray and pink colors) indicate deep and intense thunderstorms in the core. There is no evidence of an eye besides a faint dimple in the center of the convective mass.
Track map of Philippe 2005. The storm develops a good distance east of the Lesser Antilles. It then moves slowly to the north-northwest while intensifying. About one day after forming the storm becomes a hurricane, and after another day it weakens back into a tropical storm. The storm then accelerates northward, weakens further, and dissipates southeast of Bermuda.

#wxhistory #OTD in 2005: Tropical Storm Philippe forms east of the Lesser Antilles.
Philippe became a Cat 1 hurricane just over a day later as it moved north, but further deepening was hampered by persistent shear due to outflow from nearby Rita and, later, an upper low. Light rain fell in Bermuda.
#OTD in 2005: Large and slow-moving Hurricane Ophelia approaches the Carolinas. Although the storm center remained offshore, the eyewall still brought sustained hurricane winds, 4-6' of storm surge, and 15"+ of rain to parts of coastal NC over the course of 14-15 September. #wxhistory

8/26/2005 5PM EDT NHC three-day forecast cone for Hurricane Katrina. The storm is located just north of the Dry Tortugas and will curve north, roughly making landfall in Mississippi midday Monday in this forecast as a strong hurricane.
By 5PM EDT 8/26, the NHC was forecasting Katrina to reach Cat 4 intensity at landfall, noting its recent rapid organization and that it would soon cross the warm Gulf loop current.
Gov. Kathleen Blanco declares a state of emergency for Louisiana.

As the storm made its way toward South Florida, the 8/24/05 5PM ET NHC advisory was the first to explicitly show a landfall on the northern Gulf Coast at the 120hr forecast point. The Gulf landfall intensity in this forecast was 65-70kt (75-80mph, or 120-130km/h). #wxhistory
GOES-12 RGB visible image of the western Atlantic ocean. A cluster of convection is located just north of Hispaniola and Cuba, over the Turks and Caicos and central/southeast Bahamas.
NHC forecast cone for TD Twelve issued 5PM EDT August 23, 2005. The forecast track center goes northwest over the northwest Bahamas, then turns west to go over South Florida, then emerges into the Gulf of Mexico and strengthens into a hurricane. There is large uncertainty as indicated by the broad cone width.
On this day 20 years ago: Tropical Depression Twelve forms over the central Bahamas from the merger of a tropical wave and the remnant mid-level circulation of TD Ten, assisted by an upper-tropospheric trough.
The beginning of a generation-defining tropical cyclone, one named #Katrina.

Terra MODIS longwave infrared image of Jose around 04:34 UTC August 23 2005, just inland over Veracruz, about 90 minutes after landfall. The storm is much more consolidated than in the previous visible image, indicating that it organized rather quickly. It made landfall at peak intensity of 50kt (998hpa pressure).
Best track map of Jose forming in the Bay of Campeche, moving west into Veracruz, and dissipating shortly after landfall. The track is extremely short because the storm (as a tropical cyclone) formed and dissipated within 24 hours.

#wxhistory #OTD in 2005: Tropical Storm Jose forms, comes ashore in central Mexico.
Jose was the 3rd short-lived TS in 2005 to form in the Bay of Campeche and make landfall in Veracruz. The storm produced up to 10" (250mm) of rain w/ little warning lead time, causing mudslides + several fatalities.
Aqua MODIS RGB composite satellite image of TD Ten (2005) in the open Atlantic (intensity 25kt, 1009hPa at the overpass time) on Aug 13 around 15:53 UTC. The system appears as a condensed clump of bursting thunderstorms with very little symmetrical organization. Data from NASA.
Terra MODIS longwave infrared satellite image of TD Ten (2005) in the open Atlantic at peak intensity (30kt, 1008hPa at the overpass time) on Aug 14 around 01:21 UTC. The system is more consolidated into a single "cell" with overshooting tops (bright yellow colors in the middle) indicating rigorous thunderstorms, but it is still disorganized and strongly sheared. Data from NASA.
Best track map of TD Ten (2005) showing a tropical depression forming in the deep tropical Atlantic, moving slowly and slightly erratically but generally to the WNW, and dissipating in 30 hours not far from where it began. Its remnants were tracked for another ~4 days as a remnant low that dissipated close to the northern Lesser Antilles.

#wxhistory #OTD in 2005: TD Ten forms in the Atlantic main development region from an African easterly wave. Although the system lasted only a total of 30 hours, its remnant circulation would later become partly involved in the genesis of Hurricane Katrina.
Terra MODIS RGB composite image of Hurricane Irene near peak intensity (85kt, 975hPa at the overpass time) on Aug 16, 2005 around 14:56 UTC, in the open ocean about 500km NNE of Bermuda. The image shows a moderately strong and symmetrical hurricane with a clear eye except for some low-level cumulus. Two convective bursts are occurring across from each other in the western and eastern eyewall. Data from NASA.
Best track map of Irene showing a tropical depression forming in the deep tropical Atlantic, moving WNW for two days, briefly intensifying into a tropical storm (and being named Irene) then weakening back into a TD. As it passes far north of the Lesser Antilles, it regains TS strength, then intensifies more as it recurves at around 35N, 70W (around the longitude of Hispaniola). The storm reaches its peak Cat 2 strength as it moves eastward around 36.5N and dissipates about 2 days later while moving northeastward into the midlatitude open Atlantic. Plot credit Sarah Ditchek, UAlbany.
#wxhistory #OTD in 2005: Tropical Storm Irene is named, the earliest "I" storm at the time. Persevering for 14 days after becoming a TD on Aug 4 until dissipating on Aug 18, Irene was also the longest-lasting tropical system of the 2005 Atlantic season.

Terra MODIS RGB composite image of Tropical Storm Harvey near peak intensity (50kt, 995hPa) passing ~150 km ESE of Bermuda on 2005 August 4, around 14:32 UTC. The system is compact with a big convective burst occurring near the center and most of the storm activity to the north. Data from NASA.
Best track map of Harvey showing a tropical depression forming far east of Florida (~1000 km) and quickly becoming a tropical storm, passing just south of Bermuda, then traveling generally east-northeastward in the open Atlantic. The storm becomes extratropical far from land and eventually dissipates near the Azores. Plot credit Sarah Ditchek, UAlbany.
#wxhistory #OTD in 2005: Tropical Storm Harvey develops in the Atlantic. Harvey reached a peak intensity of 55kt on Aug 4 shortly after brushing Bermuda and causing minor damage. The storm became post-tropical on Aug 8 and its remnants spent the next ~five days meandering in the northern Atlantic.

24-hour rainfall map from from 08:00 July 24 to 08:00 July 25, 2005. A big patch of 50mm+ rainfall values extends across northern Veracruz, most of Tamaulipas, eastern San Luis Potosi, and southeast Nuevo Leon. There is a large gradient in precipitation outside the 50mm+ patch. Maximum 24-hr rainfall was 214.9mm in Tamuin, San Luis Potosi. Graphic from Comisión Nacional del Agua, Mexico.
#wxhistory #OTD in 2005 (local): Tropical Storm Gert forms & makes landfall in northern Veracruz, the third TS or hurricane to hit NE/east-central Mexico in a month. Heavy rain fell (up to ~8", 215mm, in San Luis Potosí) where Emily affected <5 days earlier, though damage ended up relatively limited
Terra MODIS RGB composite image of TS Franklin at maximum intensity (60kt, 1001hPa) taken around 15:47 UTC on July 23, 2005, a few hundred km NE of Abaco. The storm is basically a compact but fervent blob of convection, with no real hint of an eye. Data from NASA.
Best track map of Franklin showing a tropical depression forming east of Eleuthera and quickly becoming a tropical storm, passing very close to Abaco, then traveling generally northeastward with slightly erratic movement in the open Atlantic. The storm becomes post-tropical south of Newfoundland. Plot credit Sarah Ditchek, UAlbany.
#wxhistory #OTD in 2005 (local time): Tropical Storm Franklin is named. Despite passing close to Eleuthera and Abaco in the Bahamas, winds/rain were mostly east of center, and the storm harmlessly moved out to sea. Franklin reached peak intensity (60kt) on 7/23 and became post-tropical on 7/30 UTC.
When Emily dissipated around this time 20 yrs ago, the 2005 Atlantic season by then had reached 55.99 ACE.
I don't have ACE time series for all seasons (way too busy rn to do that), but 56 by July is high, to put it mildly. Between 1951-2020, the median ACE for an entire season was 96.7.

#wxhistory #OTD in 2005 (local time): Hurricane Emily briefly reaches Category 5 intensity, becoming the first Cat 5 storm of the season.
At the time, Emily was the earliest Cat 5 Atlantic hurricane on record until it was surpassed by over two weeks by Beryl in 2024 (July 2 00Z).
Also #OTD 20 years ago (local time): Tropical Depression Five forms in the "main development region" of the deep tropical Atlantic. 24 hours later, it will strengthen into Tropical Storm Emily.
