Tropical Depression Tracked 700 Kilometers East-Northeast of Andersen Air Force Base
Tropical Depression 28W is positioned 700 kilometers east-northeast of Andersen Air Force Base, tracking north-northwestward at a speed of 7 km/h (4 knots) over the preceding six-hour window, according to tracking data from Zoom Earth. The system registers a maximum significant wave height of 3 meters (10 feet). Atmospheric conditions, specifically extensive dry air and marginal upper-level flow tied to a Tropical Upper Tropospheric Trough (TUTT) cell and broad cyclonic flow, will maintain the system at tropical depression strength through the forecast period.
The Joint Typhoon Warning Center (JTWC) issues its track forecast using a blend of aicn, CONW, and GDMI models with medium confidence. Physics-based and AI-based model guidance show strong alignment, displaying a 232-kilometer cross-track spread at the two-day mark due to an entrenched subtropical steering ridge. Reliable intensity guidance points to a flat or steadily weakening trend throughout the forecast window.
Subtropical Ridge Steering and Consolidation Struggles
The system will move northwestward over the next two days along the southwestern edge of the low- to mid-level subtropical ridge. Persistent convergent cyclonic flow and surrounding dry air will restrict the system’s ability to organize, leading to dissipation within two days. This pattern of cyclonic flow is expected to persist directly over the system for the next two days or longer, frustrating any attempts at structural intensification.
Frequently Asked Questions About Tropical Depression 28W
What is the current movement speed and direction of Tropical Depression 28W?
The system is tracking north-northwestward at 7 km/h (4 knots) and is located 700 kilometers east-northeast of Andersen Air Force Base.
How long will the system maintain its current strength?
Forecasters expect the system to remain at tropical depression strength throughout the entire forecast period before dissipating within two days due to dry air and persistent convergent flow.
Which forecasting models did the Joint Typhoon Warning Center use?
The JTWC track forecast relies on a blend of aicn, CONW, and GDMI model guidance, supported by medium confidence.
