“Thank You, Lord — for Using Sierra Madre to Shield Our Nation”
But behind this natural wall lies a greater truth — it is God who commands the wind and stills the storm.
The Sierra Madre is merely His instrument — a reminder that creation itself moves under the authority of its Creator.

So today, we say:
Thank You, Sierra Madre — for standing tall.
And thank You, Lord — for standing above it all.

🔍 Key Facts
The Sierra Madre is the Philippines’ longest mountain range, stretching roughly 500–600 km along the eastern coast of Luzon (from Cagayan to Quezon) and covering ten provinces.
It is often described as a “natural barrier” or “shield” against typhoons coming from the Pacific Ocean because storms typically hit its eastern slopes first, giving a chance for wind and rain energy to be reduced.
One study found that the Sierra Madre does reduce wind exposure and basin‐wide rainfall particularly in the Cagayan Valley, and also has a notable “barrier effect” for eastern Bicol and Catanduanes.
However, other research cautions that the “barrier myth” is overstated: while the mountain range modifies wind and rainfall patterns (via orographic lift and friction), it does not fully stop or significantly weaken a typhoon’s core intensity in many cases.
The Sierra Madre’s protective value is also tied to its forest cover and ecological integrity: deforestation, illegal logging, and land‐use changes reduce its ability to buffer storms, absorb runoff, and stabilize soils.

✅ Implications for Typhoon Uwan & Flood Control
As Typhoon Uwan approached from the east, the Sierra Madre may have slowed the storm’s advance, caused increased friction, and altered its wind and rainfall distribution.
Because the range forces moist air to lift (orographic effect), it may have increased rainfall on windward slopes — which can translate into heavier flooding and landslide risks even if wind speeds are reduced.
The mountain range’s condition (forest cover, slope stability) directly affects how well it can manage runoff and prevent rapid flooding — degraded slopes → higher flood/landslide risk.
Relying on the Sierra Madre alone as a “magic shield” is dangerous: structural flood control, evacuation planning, early warning are still essential.
