First Alert Chief Meteorologist Mike Buresh says that the exact timing and intensity of Ian’s impact will depend on the exact location and strength of the storm when it makes landfall and therefore, is subject to change.

  • Few if any direct impacts from Ian into early Wednesday with the first rainfall -- still not necessarily directly a result of Ian (enhanced by onshore flow) -- arriving in parts of St. Johns & Putnam Co. spreading slowly from south to north. Some areas north of Interstate 10 may have little rainfall through Wed. night into Thursday morning.
  • Potential rainfall: 8-12″... 15″+ for some areas with max amounts as high as 20″ for a few areas south of I-10, near and east of I-95 and near and along the coast. The most extreme rainfall potential will be along & south & east of a line from Brunswick to St. Marys to Bryceville to Macclenny to Lake Butler.
  • Tropical moisture surging north combined with onshore winds (out of the east) ahead of Ian should begin to bring some showers, isolated thunderstorms from south to north through the day Wednesday. This will start to saturate the already wet ground across the area leading to flooding issues Thu./Fri. -- in particular -- as heavy Ian rain bands move across the area & potentially “train” across some areas. The saturated soil may also lead to trees being more easily uprooted by winds that otherwise may not be much of a problem.
  • We’ll have to keep a close eye on downtown Jacksonville as -- given the current forecast & now Ian staying south of Jacksonville before moving northward near the coast -- strong easterly flow Thursday into Friday may “pile up” water at the bend near the Acosta Bridge (where it goes from flowing to southwest then south) causing water to overflow into parts of downtown in addition to the heavy rain & high tidal departures. This situation is not exactly the same as Irma in 2017 as Irma stayed to the west causing a strong & long fetch of southerly flow up the St. Johns River into downtown Jacksonville. The current Ian forecast is somewhat more similar to Matthew in 2016.
  • Those along Black Creek and its tributaries should be aware of the flood threat & be ready to evacuate, if necessary.
  • Storm surge is expected to average at least 3-5 feet at the Florida coast and along the St. Johns River (for comparison, St. Johns River storm surge caused by Irma was 5-6 feet in downtown Jacksonville in Sept., 2017 & was 5-7+ feet during Matthew at the coast in Oct. 2016).
  • Seas & surf will increase through the week with a very high risk. Double digit breakers at local beaches can be expected Thu./Fri. with a very high rip current risk. Breakers at the beaches 5-7+ feet Wed... 10-15+ feet Thu... 8-12+ feet Fri.... subsiding over the weekend.
  • Gusty winds arrive Wed. but increase further Thu./Fri. *At the moment* tropical storm force (39+ mph) sustained winds will be possible in some areas favoring near & south of I-10 with hurricane force (74+ mph) wind gusts possible for brief times.
  • Isolated waterspouts & tornadoes can be expected Wednesday through Friday
  • At least some power outages should be expected.
  • Tuesday into early Wednesday will be your last full day to get organized, check storm kits, prepare your yard & home for a storm, check & test (understand!) generators & top off gas tanks.
