CARIBBEAN EXPOSURE

No Coastline Buffer, Just Open Ocean

Continental cities often catch a weakening storm. San Juan catches it at full strength, from any compass bearing.

Cape Verde Track

Long-fetch Atlantic systems arrive at peak intensity with nothing to slow them.

DIRECT FETCH

Maria, 2017

A Category 4 landfall reset enforcement and roof-connection standards island-wide.

CODE INFLECTION

Every Bearing

Threats run Atlantic, Caribbean and Gulf across a June-to-November season.

VELOCITY & TERRAIN

Reading the Right Speed for Bay, Beach or Block

San Juan's Risk II design wind runs 165–180 mph and varies by site. Exposure flips between coast and interior, and conservative practice favors C.

Risk CategoryMap / MRI BasisSan Juan Design Wind

II — standard occupancy700-yr map165–180 mph (varies by site)
III — assembly / schools1,700-yr mapHigher local map speed
IV — hospitals / EOC3,000-yr mapHighest local map speed

Risk category selects which map you read; there is no fixed multiplier between them. Exact mph is a function of your address.

Exposure C — Waterfront

Condado, Isla Verde, Ocean Park and Old San Juan's open Atlantic edge.

OPEN TERRAIN

Exposure B — Interior

Built-up inland blocks of Hato Rey and Río Piedras may qualify; verify the surround.
