| Message 2’s have been issued for the entire District effective until 12:00pm, Saturday August, 26th as there will be a threat of heavy rainfall today, through this evening/overnight and through midday tomorrow. Remnants of a tropical system have moved over the region today and will result in a good chance of heavy rainfall across the District. A few isolated storms have already impacted eastern portions of the District and continue to impact the area at this time. Storm coverage will increase through the morning with widespread rainfall possible by midday today. With an abundance of moisture in place, most if not all storms will be efficient rain producers. Stronger storms will have a good chance of heavy rainfall, combined with relatively slow storm motions could result in rainfall rates between 1-2” per hour at times. The best chance for storms today will be between noon and 8pm today, with storms likely decreasing in intensities after sundown. A chance linger showers remain through the overnight and into tomorrow, with an already saturated ground will keep a chance for flooding into tomorrow as off and on showers likely persist through the morning hours Saturday. |
WORST CASE SCENARIO: A strong, stationary thunderstorm, or training of thunderstorm cells will have the potential to produce up to 2.00” total in 60-90 minutes.
