TY Santi Update

Typhoon Santi was last spotted 550km East of Manila. It's packing winds of 155kph and moving west at 30kph. Outer rain bands have slowly made their way into the eastern coast of Luzon, affecting the province of Quezon and the Bicol region. Public Storm Signal Warnings are posted below. Expect conditions to deteriorate gradually in the next 6-12 hours.

Santi will make landfall at around early Saturday morning somewhere in Northern Aurora as a minimal Cat 2 Typhoon with winds reaching up to 150kph and gusts of up to 190kph. It will then track through the Central and Northern Luzon and passing through Rizal, NCR, Bulacan, Pampanga, Bataan, and Southern Zambales. It will slowly weaken as it interacts with the island, possibly weakening into a Cat 1 or even a Severe Tropical Storm. Santi should exit Luzon island by Sunday morning. The track forecast map is posted below. The areas shaded in light pink have a strong chance of experiencing more than 100kph winds.Rainfall

Typhoon Santi has a large area, and areas with signal warnings should experience prolonged moderate to heavy rains. Our 12hour rainfall forecasts show the eastern areas getting 50mm+ of rain; isolated areas could get more than 100mm. The amounts will slowly increase as Santi approaches. Legends only show up to 50mm; our next rainfall forecast will have increased rainfall amount parameters to compensate for this (i.e. 100mm+).

Wave Heights

As always, expect high surf and storm surges to occur, especially in the east coast. While Santi is just a Category 2 typhoon, waves as high as 2m or more could still be observed. Therefore, residents living in low lying areas, or more importantly, near the coast, should definitely evacuate. Sea travel is also not recommended.
Next update should be posted after 12hours (around 3am PST). Stay tuned to your local TV/Radio Station. If you're on the path of the storm, evacuation is a must. If there's no time, stack up on foods and clean water, move to higher ground; look for signs of flash floods and landslides as well.
