Is the US about to see a major decline in available goods? Looking at data for next 30 days on vesselfinder.com

I looked up the 5 largest ports on the US east coast: Seattle, Tacoma, Oakland, LA and Long Beach - and according to vesselfinder.com the incoming vessels are as follows: https://imgur.com/a/f6DE4Ad

Does anyone know if the data here really is accurate? Is Sunday a special day for incoming vessels or is for example Seattle really receiving 84 vessels in one day, and expecting less than 1 vessel a day for the next 30 days?

If these numbers truly are accurate, will this not have a major effect all over the US?
