Tropical Storm Amanda Eastern Pacific: Intensifying Cyclone with Heavy Rain and Wind Hazard
Tropical Storm Amanda is intensifying over the Eastern Pacific Ocean at 10.5°N, 128.6°W as of June 3, 2026. Located approximately 1,200 km southwest of Mexico's Pacific coast, Amanda is organizing rapidly with sustained winds exceeding 65 km/h and a well-defined low-pressure center. The storm poses an immediate threat to coastal communities across southwestern Mexico, Central America, and the southwestern United States through heavy rainfall, flash flooding, and tropical storm-force winds expected within 5–7 days. Sea surface temperatures in the region exceed 27°C, providing ample thermal energy to sustain and potentially intensify the system.
THE SCIENCE
Tropical Storm Amanda develops through warm ocean waters and atmospheric instability characteristic of the Eastern Pacific during early summer. The Coriolis effect, combined with low wind shear and high relative humidity at mid-levels, allows the system to organize into a coherent vortex. As Amanda moves northwestward, it will interact with cooler waters and increased wind shear, which typically weakens tropical cyclones but may produce significant precipitation over land before dissipation.

Thermal Engine
Warm Pacific waters (27–29°C) fuel convection and latent heat release, the primary energy source for cyclone intensification.
Oceanography
💨
Atmospheric Setup
Low vertical wind shear and high moisture allow the system to organize into a tight, symmetric circulation pattern.
Meteorology
🗺️
Regional Risk
Mexico, Guatemala, and Central America face flooding and landslides from orographic precipitation as Amanda approaches terrain.
Geography
HOW PANDITA DATA TRACKS THIS
Pandita Data ingests real-time NOAA satellite imagery, including visible, infrared, and microwave bands from GOES-17 and NOAA polar orbiters, to visualize cloud structure and precipitation rates. Microwave data penetrates convective clouds to reveal rainfall intensity; infrared channels measure cloud-top temperatures, indicating updraft strength. Our 3D weather simulation integrates these observations with atmospheric models to project storm track, intensity, and precipitation distribution, updated every 6 hours as new data arrives.
KEY FACTS: Tropical Cyclones in the Eastern Pacific
The Eastern Pacific hurricane season (May–November) produces 15–20 named storms annually. Tropical storms and hurricanes intensify rapidly over warm water but weaken quickly over land or cooler water. Forecast uncertainty increases beyond 72 hours; multiple forecast tracks should guide preparedness planning, not a single deterministic path.
EMERGENCY PREPAREDNESS
1
Secure Outdoor Objects & Plan Evacuation Routes
Remove or secure loose outdoor items (trash cans, outdoor furniture, signs) that become projectiles in tropical storm winds. Know multiple evacuation routes from your area; flooding may block primary roads. Keep a bag with documents, medications, and water ready to go.
2
Monitor Official Warnings & Stock Supplies
Check National Meteorological Services and official alerts every 6 hours. Stock 1 week of non-perishable food, bottled water (1 gallon/person/day), batteries, first-aid kits, and prescription medications before landfall.
3
Avoid Floodwaters & Flash Flood Zones
Never drive or walk through flowing water; as little as 15 cm of moving water can knock a person down. Move to higher ground immediately if rain intensifies, especially near rivers, streams, and in urban drainage areas prone to flash flooding.

FREQUENTLY ASKED QUESTIONS
What is causing this severe weather?
Warm Eastern Pacific waters (27–29°C), low wind shear, and atmospheric instability allow Amanda to organize into a coherent tropical storm system.
What are the greatest hazards from this storm?
Heavy rainfall and flash flooding in Mexico and Central America; tropical storm winds; potential landslides over mountainous terrain from orographic precipitation.
What precautions should people take immediately?
Secure outdoor objects, stock food/water/medicines, monitor official alerts every 6 hours, and identify evacuation routes; move to high ground if flash flooding begins.
