POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for rainfall flooding having possible extensive impacts across. Potential impacts include: - Major rainfall flooding may prompt many evacuations and rescues. - Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, canals, arroyos, and ditches may become dangerous rivers. In mountain areas, destructive runoff along steep terrain will result in many rockslides and landslides. Flood control systems and barriers may become stressed. - Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out. Prepare for dangerous rainfall flooding having possible limited to significant impacts across the US Virgin Islands. * WIND: Prepare for dangerous wind having possible significant impacts across the US Virgin Islands. Potential impacts in this area include: - Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. - Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable. - Scattered power and communications outages, but more prevalent in areas with above ground lines. * SURGE: Prepare for locally hazardous surge having possible limited impacts across the US Virgin Islands. Potential impacts in this area include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. * TORNADOES: Prepare for a tornado event having possible limited impacts across USA Virgin Islands. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. Elsewhere across Puerto Rico and the US Virgin Islands, little to no impact is anticipated. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: Now is the time to check your emergency plan and take necessary actions to secure your home or business. Deliberate efforts should be underway to protect life and property. Ensure that your Emergency Supplies Kit is stocked and ready. When making safety and preparedness decisions, do not focus on the exact forecast track as there are inherent forecast uncertainties which must be taken into account. If you live in a place that is particularly vulnerable to high wind, such as a mobile home, an upper floor of a high rise building, or on a boat, plan to move to safe shelter. Take enough supplies for you and your family for several days. If you live in a place particularly vulnerable to flooding, such as near the ocean or a large inland lake, in a low lying or poor drainage area, in a valley or canyon, or near an already swollen river, plan to move to safe shelter on higher ground Always heed the advice of local officials and comply with any orders that are issued. Do not needlessly jeopardize your life or the lives of others. When securing your property, outside preparations should be conducted as soon as possible before conditions deteriorate. The onset of strong gusty winds and heavy rain can cause certain preparedness activities to become unsafe. Be sure to let friends and other family members know of your intentions and whereabouts for surviving the storm. For emergency purposes, have someone located away from the threatened area serve as your point of contact. Share vital contact information with others. Keep cell phones handy and well charged. Be a Good Samaritan and check on those who may not be fully aware of the situation or who are unable to make personal preparations. Visitors to the area should become familiar with nearby surroundings. If you are a visitor, know the name of the county or parish in which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors. Closely monitor NOAA Weather Radio or other local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in San Juan PR around 5 AM, or sooner if conditions warrant. $$
