* LOCATIONS AFFECTED - Burns Point - Cypremort Point * WIND - LATEST LOCAL FORECAST: Below tropical storm force wind - Peak Wind Forecast: 20-30 mph with gusts to 40 mph - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Wind less than 39 mph - The wind threat has remained nearly steady from the previous assessment. - PLAN: The sustained wind should remain less than tropical storm force. Conditions may still be gusty. - PREPARE: Listen for any instructions from local officials. - ACT: Ensure emergency readiness should the forecast change. - REALIZED IMPACTS: Being Assessed - Little to no additional wind impacts expected. Community officials are now assessing the extent of actual wind impacts accordingly. * STORM SURGE - LATEST LOCAL FORECAST: Localized storm surge possible - Peak Storm Surge Inundation: The potential for 1-3 feet above ground somewhere within surge prone areas - Window of concern: Begins this afternoon - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm surge flooding greater than 1 foot above ground - The storm surge threat has decreased from the previous assessment. - PLAN: Plan for storm surge flooding greater than 1 foot above ground. - PREPARE: Efforts should now be underway to prepare for storm surge flooding, especially in low-lying vulnerable areas. - ACT: Take actions to protect life and property. Prepare to leave if evacuation orders are given for your area. - POTENTIAL IMPACTS: Limited - 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. * FLOODING RAIN - LATEST LOCAL FORECAST: Flood Watch is in effect - Peak Rainfall Amounts: Additional 1-3 inches, with locally higher amounts - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for moderate flooding rain - The flooding rain threat has decreased from the previous assessment. - PLAN: Emergency plans should include the potential for moderate flooding from heavy rain. Evacuations and rescues are possible. - PREPARE: Consider protective actions if you are in an area vulnerable to flooding. - ACT: Heed any flood watches and warnings. Failure to take action may result in serious injury or loss of life. - POTENTIAL IMPACTS: Significant - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. * TORNADO - LATEST LOCAL FORECAST: - Situation is favorable for tornadoes - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for several tornadoes - The tornado threat has increased from the previous assessment. - PLAN: Plans should still include the potential for several tornadoes. - PREPARE: Keep informed should additional weather alerts be needed. - ACT: If a tornado warning is issued, be ready to shelter quickly. - POTENTIAL IMPACTS: Significant - The occurrence of scattered tornadoes can hinder the execution of emergency plans during tropical events. - Several places may experience tornado damage with a few spots of considerable damage, power loss, and communications failures. - Locations could realize roofs torn off frame houses, mobile homes demolished, boxcars overturned, large trees snapped or uprooted, vehicles tumbled, and boats tossed about. Dangerous projectiles can add to the toll.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
