Real-time coverage of severeStorms event — Tropical Storm Hernan — Pandita Data.
⛈️ OPEN LIVE 3D WEATHER ALERTSTropical Storm Hernan intensified over the Eastern Pacific on August 14, 2026, positioned 15.6°N, 132°W, with maximum sustained winds near 45 knots and rapid organization potential. The system poses significant wind and precipitation hazards to Mexico's Pacific coast and offshore maritime operations across the eastern tropical Pacific basin.
Hernan's track places it in a region of warm sea-surface temperatures (28–30°C) and low wind shear, conditions favoring rapid intensification over the coming 48–72 hours. Coastal communities in Jalisco, Nayarit, and Sinaloa states face escalating risks of tropical-storm-force winds, heavy rainfall triggering flash flooding and mudslides, and dangerous seas. Shipping and offshore energy operations must implement storm protocols immediately.
Tropical cyclones form over warm ocean water when atmospheric instability, sufficient Coriolis force, low wind shear, and high relative humidity align. Hernan's position in the Eastern Pacific, near 15°N latitude, provides adequate Coriolis influence for spin-up; sea temperatures exceed the 26.5°C threshold required for sustained convection. The storm's current organization—a developing low-level circulation and banding structure—indicates the system is transitioning from tropical depression to organized tropical storm.
Moisture-laden trade winds feed convection; latent heat released during condensation intensifies vertical motion and strengthens the circulation. As Hernan moves northwestward, it will encounter the Mexican coast or cooler waters, both factors that may halt intensification and trigger weakening over land or the cool California Current.
Pandita Data's real-time weather simulation integrates NOAA satellite imagery, wind-field analysis, and atmospheric pressure data to visualize storm structure, rainfall potential, and track uncertainty. Microwave sensors detect the low-level circulation; infrared channels measure cloud-top temperature, a proxy for convection intensity.
