For the High Surf Advisory, large breaking waves of 8 to 10 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents.
WHERE
Along west-facing reefs.
WHEN
Until 4 PM ChST Monday.
IMPACTS
Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water.
ADDITIONAL DETAILS
A combination of the remnant monsoon surge and Tropical Depression 19W, well northwest of Yap Island, are producing a long-period southwest swell of 7 to 8 ft capable of high surf and dangerous rip currents along west-facing reefs. Conditions may begin to subside Monday night, so conditions will continue to be monitored.
Recommendations
Rip currents will be life threatening. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Rip currents will be life threatening. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.

...TYPHOON SAUDEL INTENSIFYING RAPIDLY SOUTHEAST OF AGRIHAN... .NEW INFORMATION... Damaging winds are imminent or occurring in Alamagan, Pagan and Agrihan. .AREAS AFFECTED... This local statement provides important information and recommended actions for people in the Northern Marianas. .WATCHES/WARNINGS... A Typhoon Warning remains in effect for Pagan and Agrihan. Typhoon conditions, including damaging winds of 74 mph or more, are imminent or occurring. A Tropical Storm Warning and a Typhoon Watch remain in effect for Alamagan. A Tropical Storm Warning in conjunction with a Typhoon Watch means that tropical storm conditions, including damaging winds of 39 to 73 mph, are imminent or occurring, and typhoon conditions, including damaging winds of 74 mph or more, are possible in the unlikely event that Typhoon Saudel moves far enough west of its forecast track. .STORM INFORMATION... At 8 AM ChST...the center of Typhoon Saudel (17W) was located near latitude 17.5N...longitude 146.9E. This was about 70 miles east of Alamagan. Storm motion was northwest, 325 degrees, at 15 mph. Storm intensity was 90 mph. .SITUATION OVERVIEW... Tinian and Saipan should soon receive the all clear if they haven't already. Typhoon Saudel is nearly atop Alamagan, Pagan, and Agrihan.
Recommendations
The threat for damaging winds from Typhoon Saudel is now zero. Typhoon Saudel never made a sufficiently large wobble to the west. .WIND INFORMATION... West to southwest winds of 15 to 25 mph will continue through Sunday. These will then diminish slightly as we fall into an ongoing monsoon pattern. .COASTAL INUNDATION AND SURF INFORMATION... Surf will be hazardous 7 to 10 feet along north and east facing reefs. This will later shift to north and west facing reefs after Saudel crosses the island chain. Coastal inundation is not expected. .OTHER STORM EFFECTS... Tinian and Saipan could receive up to 2 inches of rain from the outer bands of Typhoon Saudel as it passes by through Sunday. They may see more rain from the monsoon surge flowing into Saudel that will develop next week.

ESFGUM This Hydrologic Outlook is for Guam, Rota, Tinian, and Saipan. A reinvigorated monsoon trough with a potential embedded tropical disturbance will likely develop in the area and bring periods of heavy rainfall to the Marianas starting midweek. Between Wednesday and Friday, early ensemble guidance suggests 4 to 6 inches with a low probability of up to 10 inches for Guam and Rota, and 3 to 5 inches with a low probability of up to 8 inches for Saipan and Tinian. Heavy showers will moisten soils throughout the event and increase potential for mudslides. Residents of the Marianas need to closely monitor this developing situation as flood watches, advisories and flash flood warnings could be issued later. If living near streams and rivers, prepare to move items away from stream and river banks. Make sure storm drains nearby are not clogged, especially If living at low-lying areas.
