JOSEPHINE (AL102026)

Type: SS Max Wind: 55 kt Min Pressure: 988 hPa Position: 39.5, -66.8 Basin: North Atlantic
ZCZC MIATCDAT5 ALL TTAA00 KNHC DDHHMM Post-Tropical Cyclone Josephine Discussion Number 5 NWS National Hurricane Center Miami FL AL102026 500 PM AST Thu Oct 22 2026 The convective cloud pattern of Josephine now resembles that of a warm frontal band, with little evidence of tropical-cyclone like curvature. In addition, the circulation center is becoming elongated and cold-air clouds are increasing in the southern semicircle. Based on these developments and the earlier scatterometer pass showing a developing frontal boundary, Josephine has become an extratropical cyclone. The initial intensity is set at 55 kt, and this could be conservative. The initial motion is now faster toward the northeast or 055/15 kt. Josephine should move generally northeastward with some increase in forward speed tonight, followed by an eastward turn as it becomes well embedded in the mid-latitude westerlies. On the forecast track, the center of Josephine will move away from the New England states this evening and pass south of Nova Scotia and Newfoundland tonight and Saturday. The guidance is again tightly clustered, and the new forecast track is similar to the previous forecast. Josephine is expected to strengthen as an extratropical low tonight due to the influence of an amplifying mid- to upper-level trough over eastern Canada and the New England states, with winds reaching hurricane force. After tonight the global dynamical models are in good agreement that the cyclone should steadily weaken, and they forecast Josephine to dissipate by 72 h as it is absorbed by a new low pressure area developing to its northeast. The new intensity forecast is based mainly on the global models and again has only minor adjustments from the last forecast. The wind radii forecasts have also been revised based on the global model forecasts. This will be the last advisory on Josephine issued by the National Hurricane Center.

VANCE (EP222026)

Type: TS Max Wind: 60 kt Min Pressure: 991 hPa Position: 10.3, -101.7 Basin: East Pacific
ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM Tropical Storm Vance Discussion Number 7 NWS National Hurricane Center Miami FL EP222026 900 PM CST Thu Oct 22 2026 Satellite imagery indicates that Vance continues to become better organized, with an expanding Central Dense Overcast, a well-defined curved convective band wrapping into the circulation from the south, and cloud-top temperatures as cold as -85 C. Upper-level outflow remains well established, and recent microwave imagery reveals an improvement in the inner-core structure compared to several hours ago. The latest subjective Dvorak intensity estimate from TAFB was T4.0/65 kt, in good agreement with UW-CIMSS objective estimates ranging from 55 to 65 kt. Given these estimates and the continued improvement in satellite presentation, the initial intensity is raised to a conservative 60 kt. Vance has turned northwestward, and the initial motion is estimated at 325/5 kt. The cyclone should continue moving northwestward along the southwestern periphery of a mid-level ridge extending over Mexico into early Friday. A gradual turn toward the north-northwest is expected during the next couple of days as the ridge weakens in response to an upper-level trough over the southwestern United States. The latest track guidance remains in good agreement through about 60 h. Thereafter, the trough is expected to shift eastward, leaving Vance in a region of weaker steering currents and resulting in increasing spread among the guidance solutions. The regional hurricane models and GFS favor a more westward track away from the coast between days 4 and 5, while the GDMI, HCCA, TVCN, and ECMWF maintain a more north-northwestward track toward the southwestern and west-central coast of Mexico. Given these persistent differences in the extended guidance, the NHC track forecast is largely unchanged from the previous prediction and remains close to the GDMI and HCCA aids. Environmental conditions are expected to remain favorable for significant strengthening during the next couple of days, characterized by warm sea surface temperatures, low vertical wind shear, and plenty of mid-level moisture. Guidance continues to indicate a high likelihood of rapid intensification (RI), with probabilities from the GFS- and ECMWF-based statistical guidance reaching 65 to 80 percent during the next 24 h, well above climatological values. Accordingly, the NHC intensity forecast explicitly calls for RI during the next 24 h, with Vance forecast to become a major hurricane by early Saturday. Thereafter, the cyclone could encounter relatively cooler waters, potentially influenced by upwelling associated with recent tropical cyclones, along with increasing vertical wind shear. These factors should limit further strengthening and support gradual weakening beginning around 60 h. The NHC intensity forecast is similar to the previous prediction and remains near the upper end of the guidance envelope through much of the forecast period.

ECMWF 10-m Streamlines

This map visualizes near-surface winds from the ECMWF operational model using streamlines — continuous curves that show the direction of the wind at every point. Streamlines help us visually detect patterns of atmospheric flow, such as jets, troughs, and areas of rotation.

Forecasters at the NHC monitor 10-meter wind fields for signs of a closed low-level circulation — a common feature of early tropical cyclone formation. When streamlines wrap into a tight, circular pattern and form a closed loop, it may signal that a system is transitioning from a disorganized disturbance into a structured cyclone.

This early organization of wind flow is a key threshold in classifying an area as a potential tropical cyclone. While other ingredients like convection and mid-level humidity are also necessary, closed low-level circulation is often the first structural milestone forecasters look for.

Look for small, circular loops in the streamlines over oceanic regions — especially where other environmental factors also align for storm formation.

Environmental Indicators

Hypothetical TC Drift Paths

This map displays hypothetical tropical cyclone (TC) paths projected from genesis-favorable zones identified by an environmental mask. These paths are computed using the Emanuel Beta and Advection Model, a physically based framework that estimates the motion of nascent cyclones by combining steering-level winds and planetary rotation effects.

The model blends winds from two critical pressure levels — 850 hPa (lower troposphere) and 250 hPa (upper troposphere) — weighted toward the lower level where most of a tropical cyclone's mass resides. It also incorporates a background component associated with beta drift, which arises from the variation of the Coriolis force with latitude.

Each pink trajectory represents a storm initialized from a grid cell where all five environmental thresholds were favorable: high CAPE, low vertical wind shear, high mid-level humidity, warm SSTs, and positive low-level vorticity. Arrows darken with time, tracing the cyclone’s evolution in 6-hour steps. These tracks can move over land given the steering winds, but in reality these storms weaken quickly when no longer over warm water. This means the tracks that move over significant would likely die out quickly and are not well represented in this model.

Hypothetical storms often drift westward and poleward, steered by large-scale tropical flow and Earth's rotation — this helps forecasters anticipate where early-stage disturbances might evolve into organized storms.

TC Drift Path Map

Pressure & Rainfall (hPa)

This chart shows 24-hour forecasts of surface pressure (in hPa) and precipitation (in mm) for select U.S. cities. The data comes from the Open-Meteo API, which sources its predictions from high-resolution numerical weather models like ICON (from the German Weather Service) and ECMWF's IFS. These are advanced general circulation models (GCMs) that solve physical equations governing the atmosphere — including thermodynamics, fluid motion, and radiation — to simulate and forecast future states of weather.

A sudden drop in pressure may signal the approach of a developing storm system. Increasing rainfall intensity often tracks with tropical activity or frontal systems. These paired indicators help visualize evolving atmospheric instability and potential hazards.

NBDC Gulf Buoy Data

This data comes from the National Data Buoy Center (NDBC), a division of NOAA responsible for monitoring ocean and atmospheric conditions using moored buoys, coastal stations, and drifting floats. These sensors play a vital role in tracking tropical cyclone development by recording variables like wind speed, barometric pressure, air & sea surface temperatures, and wave height — all of which help determine storm structure and intensification.

A sudden drop in sea-level pressure or a spike in wind gusts can signal rapid cyclone strengthening. Water temperature above ~26°C is a key fuel source for tropical cyclones. Wave and swell height give insight into the storm’s reach and energy transfer across the ocean. Monitoring these in real time helps improve forecasts and early warnings.

NWS U.S. Radar

The National Weather Service (NWS) collects radar data using the NEXRAD (Next Generation Radar) network — a nationwide system of over 150 high-resolution Doppler radar stations. Radar works by emitting pulses of energy that bounce off precipitation (like raindrops, hail, or snow) and return to the radar dish. Doppler radar not only detects the location and intensity of storms, but also their motion — by measuring shifts in frequency caused by movement of particles toward or away from the radar site. This allows meteorologists to spot rotating storms and potential tornadoes in real time.

GOES 15-min Satellite

The GOES (Geostationary Operational Environmental Satellite) system is operated by NOAA and provides continuous weather observation over the Americas. Orbiting 22,300 miles above Earth, GOES satellites deliver high-resolution imagery every 15 minutes, helping track tropical systems, cloud formation, and atmospheric motion in real time. The Geocolor imagery shown here combines visible and infrared data to highlight clouds, land, and sea in a natural-looking format.

GOES Band 13 – Infrared (IR) Imagery

Band 13 (10.3 µm) is one of the most important infrared channels for tropical meteorology, measuring emitted radiation from cloud tops. Colder colors (red, yellow) signal deep convection, where strong thunderstorms punch through the upper atmosphere. These features often indicate the early stages of tropical cyclone formation.
