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 11 AM AST, or sooner if conditions warrant. $$
